Q&A
Topics in Blue are included in the interactive Richpanel FAQ Section on Taikoaudio.com
Can we keep the existing house router/wifi access point and use the Taiko router in series and create an audio-exclusive connection to the hifi system for best sound?
Yes, you can indeed.
So, you can just use your house wifi?
Indeed.
Should the Taiko Switch and Router be used in series? Or just one vs the
other?
They should indeed be used in series, the Router feeding the Switch.
Is the Router made from a solid copper billet?
Indeed, it is. We are slowly but surely moving towards 100% in house
manufacturing to get rid of external supplier dependencies as those have
become increasingly “troublesome”. We don’t want our own anodizing facility
hence the choice to move away from Aluminum as a base material. Copper is a
material which we can finish ourselves (over time), we have years of
experience working with it by now, and as a bonus, the material has an
arguably “higher-end” look and feel.
Do these cases provide full Faraday shield insulation?
They come as close as you can get for an electronic appliance.
I have the service provider fiber going into the Fiber modem, then a RJ45
cable to the router/switch. Does the new router accept the service provider
fiber directly? Or will I still need a fiber modem before the Taiko router?
The Taiko Router could accept the service provider fiber directly.
Subsequently, you could create a separated audio and rest-of-home network.
Alternatively, it could also be placed behind the fiber modem. However, we
recommend using copper.
For those of us that use an Edge router with our ATT (AT &T) setup, will
the Taiko router replace or be an addition to the network chain?
Initially, the Taiko Router will be an addition.
Does the router also have to be near the Switch, like the case for Switch
to Extreme?
No, it can be placed anywhere.
Power Switch or Router from the upcoming BPS?
It would be much more beneficial to power the switch from the BPS than the
router. We’re assuming the switch being placed close to the Extreme and the
router at a distance, likely where your internet enters your home. But this is
not the only possible scenario.
Does the Taiko router also work as a modem?
For now, it does not. But it has the potential to possible be deployed that
way at a later stage. Depending on your definition of modem, yes, but your
service provider needs to permit and support using your own router.
Does the Taiko router also work without wifi?
We will prep the Router for Port Forwarding to allow using tablets via your
regular Access Point but that does perform less well than the built-in wifi.
Can we use the router instead of the switch? In other words, does the
router do everything the switch does, and more?
No, they serve different purposes.
Are you going to do some testing with the major ISPs in each region to see
which work with your router? (in case one wants to replace the existing AP
with the Taiko Router)
Unfortunately, this is not realistically executable. Also, this is premature
and for potential future purpose. Our current configuration is to use the
Taiko Router in series, after the main router/wifi access point.
Since my ISP’s Router also works for TV services, I need to place the Taiko
Router after my ISP’s Router. In this case, would we make a LAN-to-LAN
connection with the Taiko Router’s DHCP services disabled, or a LAN-to-WAN
connection creating a second network for audio only?
Creating a second network for audio only would give you the maximum uplift in
Sound Quality. This yields much quieter backgrounds, undisturbed by network
traffic generated by other persons in the household.
Can you rank the various Taiko products by order of magnitude of
improvement of the sound quality?
The Taiko Audio Extreme Switch is the star of the “show”. In order of impact
as things are today:
- Switch
- XDMS
- Router
- Network card + Interconnect
But it’s a tight race between 1) and 2).
Is there any sonic advantage to have the router and the switch in separate
boxes? If not, could you possibly offer a one-box router-switch so we
eliminate one cable and possibly one external power supply?
Unfortunately, yes there is an advantage to having separate boxes. If you want
just one box, we recommend picking the switch.
Although we can have separate networks assigned within the Taiko router,
will it still be better to have a separate ISP Fiber and modem to fully
isolate traffic?
This can actually turn out negative. For obtaining a degree of separation, you
could place the modem, router, and switches on a separate mains system. But if
you’re splitting a single phase with a common neutral it’s not going to matter
that much.
Which of RJ45 or Fiber would work best with the Taiko router?
RJ45 is preferred but both work well.
What are the rated speeds of the Router’s RJ45 ports?
1Gbps (but the RJ45 ports also work with 100Mb connections)
What is the rated speed of the Router’s SFP ports?
1Gb (incompatible with 100Mb connections)
Why do the SFP ports only work with 1Gb?
SFP modules and -ports are designed for a single speed and they do not exist
in a dual-speed configuration. The SFP modules and ports that we use in our
Taiko Audio products are specified to work only at 1Gb.
As a result, the following Taiko Audio products will not work with 100mb
connections, only with 1Gb connections:
• Extreme Switch
• Extreme Network Card
Conversely, RJ45 ports can work in 100Mb and 1Gb mode. As a result, the Taiko
Audio Extreme Router will be partially compatible with 100Mb and 1Gb
connections:
• Extreme Router RJ45 ports: 100Mb and 1Gb
• Extreme Router SFP/DAC port: 1Gb only
What this means is that any network interfaces upstream of the Taiko Audio
Extreme Switch or Network Card, such as generic routers or switches, must be 1
Gb. For the Taiko Audio Extreme Router, the same holds true where it concerns
devices connected to its SFP/DAC port.
Please note that some Ethernet cables are restricted to 100Mbit (as opposed to
Gigabit) which will also be incompatible.
Will the Router work with a MESH satellite router such as the Asus zenwifi?
Will it meet the 1GB requirement?
The Extreme Router accepts either 100Mb or 1Gb on its RJ45 ports, so as long
as the Extreme Router is used upstream of the Switch and NIC, the setup will
work.
Is there a chance to add second SFP port in router?
No, that is not necessary. The benefit OF SFP is a reduction of the switch
power consumption by switching out a RJ45 port for SFP DAC which is the
dominant form of noise generation in this switch design. What happens before
is much less relevant in this area. The Router is designed to work optimally
as it is with the partial isolation a rj45 input provides from a “noisier”
upstream environment being beneficial in this case.
Will the Taiko Router support creating a V-LAN upon installation?
Yes, this is indeed supported.
Within a voltage range, what is the best voltage?
The largest variation in that would be caused by a linear Power Supply. For a
LPS, a higher voltage might be better as most are noisier at higher currents
(and lower voltages).
If 12V is optimal for the Switch (which is its minimum recommended
voltage), would 7V also be best for the Router, given that’s its lowest
recommended voltage?
The issue here is the LPS. Both the Switch and Router are very power
conversion efficient (~99%). That means that if the power consumption would be
12 watts (just as an easy example), the current draw would be 1A as
voltage*current=power. If you use a 7V supply the current would go up to 1.7A
(12W divided by 7V = 1.7A). Typically, higher current = higher noise in a
linear regulator, but there’s more to it than that. A LPS is not a very power
efficient supply. As a commercial manufacturer you would not typically use a
different transformer for each different output voltage. Perhaps you’d use a
15V AC secondary transformer which supplies about 21V DC after rectification
(+/- 10% to account for wall voltage variations) for 15V and 12V out after
regulation, in a LPS the excess voltage is discarded, transformed into heat,
increasing the current draw from your power grid, and the current spikes for
recharging the capacitor bank which is also a type of noise, the more
inefficient it is (the more power is transformed to heat) the worse this gets.
So, it just depends on the LPS design which voltage will perform best. As 12V
is a very common voltage you could assume those to be relative efficient
designs, but in the above example with a 15V AC transformer secondary the 15V
LPS could perform “better”. Now if a manufacturer uses the same transformer
for a 5V, 7V and 9V supply, the 9V would be most efficient. Therefor it’s
impossible to give you an exact recommendation without knowing the design
specifics of the LPS as the Switch and Router really don’t care much which
voltage is supplied as long as it’s in range.
Is it true that some audiophile cables do not work with the Taiko NIC and
Switch?
Cables that are restricted to 100Mbit (as opposed to Gigabit) can indeed cause
certain issues. Although reducing the network speed to 100Mbit is a strategy
employed by some “Audiophile” switches with a school of thought that lower
speed translates to lower noise this is not the Taiko way. Further to this,
many “unexplained” Roon problems, like sudden stops during playback are caused
by 100Mbit network speeds and solved by moving up to 1Gb, with a vast decrease
in error messages in Roon’s logs. For XDMS, the negative impact on SQ by
running at 100Mbit is very obvious. Therefore, we do not support 100Mbit
networks, but we do support diagnosing and curing the cause of running a
100Mbit network.
100Mbit versus Gigabit Switches - what’s better?
if you look at it from a design / component perspective, 1Gb switches are much
more modern / advanced / further developed, and can actually end up consuming
less power overall than antiquated 100Mbit switch chips. Our switch only uses
1.3 watts with DAC cables? We did not have much success with 10Gb though, that
just uses way more power, runs much hotter and is very difficult to get to
sound right.
RJ45 or DAC?
We prefer DAC for ultimate neutrality, transparency and imaging precision.
RJ45 is a close second above Glass. Some people prefer a degree of “smoothing”
which makes a case for using RJ45 that can sound more pleasurable and reduce
harder edges caused elsewhere in the system compared to DAC.
Is the customized QoS rule of the router important?
Yes, virtually all settings matter.
I will replace my current switch (before the Extreme) with the Taiko
switch. Should I also remove the subnet (Edge Router x) before that?
Yes, the Taiko router should be able to do everything the Edge Router x does.
However, there are some ISP devices that will prohibit direct one-on-one
replacement. In that case, you can add the Taiko Router after the ISP Router.
Will the router and switch also be made available for non-Extreme users?
Never say never, but initially, the Taiko Audio Router will be available only
to Extreme owners. With some adjustments it’s possible for non-Extreme owners
to use but it will not give the full benefit, which includes a software /
firmware interaction. As it stands, it was quite a challenge to secure enough
parts to be able to supply one to each current Extreme owner and have a few
spares for future ones.
With the Taiko router in place, is there still a benefit to isolating the
audio Wi-Fi AP with fiber optic?
Not in the cases that we have tried it.
Copper or Fiber Networks? I have two separate internet services in my home,
one is fiber, going to the Audio Network, and one is copper, going the home
network, so they are completely isolated. In this case, which option should be
better:
a) Program (if possible) the Taiko router in order to use it directly with
the fiber input
b) Keep the current fiber modem and router, and place the Taiko router in
series
In this case, it doesn’t matter much. Although we do significantly prefer rj45
into the router though so we would probably end up recommending b) for that
reason.
Will it be possible add two sets of rules to the Router?
The first set of rules : complete isolation. The second set of rules :
allows access to the HiFi network from the Home network. The goal being to
backup the music files and the Roon library from the Extreme to a NAS located
in the home network and to access the Extreme’s Roon server from a machine on
the home network to allow managing Roon settings and library from a desktop
machine.
We can add VNC and filesharing port forwarding rules, but keep in mind less is more for SQ. We are contemplating implementing VNC and file share access port forwarding, preconfigured by default. The Extreme could be assigned a permanent IP address, always the same, on all routers. That adds the benefit of decreasing support load for us. Your VNC / file share access IP address from your home network would then become the IP address assigned to the Taiko router by your home network router.
If I play local files from a NAS, the NAS will connect to Taiko router.
Will it compromise sound quality?
Yes, a better solution would be to connect an USB drive to one of the Router’s
two USB A ports which can then serve as a NAS.
Can the Taiko Router server as a NAS?
It has built-in NAS functionality by means of external USB drive.
Generally, it is best to use fewer power supplies, so bus powered would
potentially be ideal, although we have not ran extensive comparisons yet. The
best solution would probably be powering it from the DC distributor but that
would typically run at 12V and most external USB drives run at 5V.
Currently, I have dedicated for audio ISP service (fiber) with modem and
Router. Home is on totally separate Service with its own modem and router.
Could I use just one ISP service, one modem and one router when using Taiko
router and the SQ will be same as on totally separated chains?
The Sound Quality should be roughly the same indeed.
I use a separate computer (MacBook Pro) to copy CDs to the Extreme SSD and
then copy to an NAS for backup. I do not use the NAS for playback. Is SQ still
affected by having the MacBook Pro and NAS connected to the Taiko router?
Yes, as they will then increase network activity on the “audio” network. Every
powered-on device connected to a network creates network activity. Most mobile
devices, like iPhones, iPads or Android devices even create network activity
in “standby / screen switched off” mode. If you power off your MacBook Pro
during music playback it should not generate network activity, but your NAS
will for sure.
At what minimum distance should the wifi AP be placed?
We don’t think the “airborne” part of Wi-Fi impacts anything. It’s more the
power side of it which can cause some “discomfort”. So, the placement is
arbitrary.
Is wifi noise not an issue?
There is most definitely a very significant impact of “wifi pollution”. But
the consensus here currently is that the negative effect is likely not caused
by a router’s 2.4/5/6Ghz radio function. In our experiments, anything below
2-3MHz affects sound by not yet fully understood mechanisms. Above that, it
does nothing audible. A wifi access point does use a variety of high
efficiency switchers emitting pollution in this range, 500-700KHz is a very
common range for example.
What about WAP?
The router will not provide WAP
How would you compare the impact of adding the router (along with isolating
the Extreme on its own network) on top of the switch to the effect we
experienced with just adding the switch and network card?
Although they impact sound quality in different ways, we feel the distribution
is as follows.
Setting 100% improvement as a baseline (actual improvement subject to your
perception), Network card and Switch combined 60%, Router 40%, drilling down
further, Network card 20%, Switch 40%, Router 40%.
This however does not include the new Extreme DC power distributor, which
allows you to power both Switch and Router from one single power supply with
significant improved performance over using 2 power supplies with the
additional option to tailor the sound to your personal preference.
It was mentioned previously that ports would be forwarded eg. for VNC to
copy files. Will there also be port forwarding for XDMS, so I can control my
music from my Macbook while still being connected to the main (non-audio)
router, which I need for accessing the internet?
With our recent breakthrough in finding a solution to add wifi to the router
without sonic sacrifices (rather the inverse), port forwarding is no longer
needed, as the control point/tablet simply connects to the Extreme server
directly. However, we will prep the Router for Port Forwarding so that you can
still use the Extreme as you’re used to, using your home wifi, using Roon,
XDMS, VNC, Teamviewer and file sharing.
Would network noise be more prevalent in congested areas such as apartment
complexes, cities, developed areas? Or is network noise inherent no matter
what?
I think we’ve all been conditioned into believing in something which does in
fact not exist. There’s no such thing as “internet noise” traveling through
your home router. There’s noise caused BY activity due to the need to process
more network packets, more processing means more noise in the device
performing the processing. Naturally there’s download speed, where it takes a
longer or shorter time to receive the requested data, which translates into
longer lower intensity processing, or shorter higher intensity processing,
creating a different noise spectrum.
More Processing Means More Noise?
Adding the switch reduces processing in the Extreme, adding the router reduces
processing in both the switch and the extreme.
Isn’t a wall-wart power supply good enough for the Taiko Switch and
Router?
It is only good enough to get you started. We strongly recommend using a LPS.
1 LPS powering switch and router, when using a DAC cable as the interconnect,
“sounds” better then 2, even more so when using the DC distributor.
Will a second Taiko Router obviate the need for a good quality LPS?
Unfortunately, no.
Is port forwarding (on the Taiko Router) the preferred method to enable the
iPad to control the Extreme wirelessly?
Previously yes, currently no longer. Onboard wifi is now preferred.
Will port forwarding cause lag with XDMS?
Functionally, you won’t notice a difference.
What needs to be configured to make Port Forwarding function?
The Router will be preconfigured for port forwarding. (you may need to change
a setting), then move the ethernet cable from switch to router and insert the
DAC cable between router and switch, and that’s it.
Is it going to be the general recommendation that the router connect to the
switch via a DAC cable?
For ultimate “neutrality” and in the large majority of use cases, yes, but it
works great with rj45 as well.
Is there a clear preference between RJ45 or DAC cable to connect the Router
to the Switch, when the they are on their own individually-isolated Shunyata
Denali receptacle, and all grounds are connected to the ALTAIRA, and not using
the DC Power Distributor?
In this particular use case, you may prefer RJ45. In that particular setup you
may want to avoid directly connecting the switch and router grounds with a DAC
cable, even though it’s the superior method of connection. If you use 2 power
supplies there will be a noise voltage “riding” on the ground connections
between the connected devices. You can then try to reduce that by different
“grounding” schemes to try to get closer to single point grounding, but as
these devices are both externally powered you can simply achieve superior
single point grounding by using 1 shared power supply.
Is there any advantage for the dirty side router to have a VLAN for the
Taiko router to connect and run off of?
No, there is not.
Is it advisable to also connect product X to the Taiko Router, in addition
to the Extreme?
it is advised not to connect anything else to the Taiko router. Not because
the device may not benefit itself, but because it may (and likely will) cause
a degradation in the SQ of the Extreme. If you leave the extra component
connected and in standby, then it depends on what the ATVX generates in
standby and how much it, including its power supply “dumps” onto the network
cabling.
Is there any provision to maintain Roon distribution for non-critical
listening? With Roon’s broadcast and multicast for discovery, Can Roon on a
Taiko Extreme “talk” to the other devices on the separate subnet?
This could be possible “with a pass-through” but this would need to be tested
in several configurations for SQ. However, the purpose of the Router is to
decrease network traffic on an “audio only” / “isolated” subnet. The more
traffic you pass through, the less “useful” it becomes.
Would you recommend using one of the router’s USB ports to connect a
USB/Ethernet converter if an additional port is required? Wondering if this
has an impact to SQ?
That will have an impact on sound quality, plus you’ll need to have driver
support in the router for that particular device.
It was stated that the length of DAC cable from switch to Extreme should be
shortest useable length. Does the same rule apply for a DAC cable from router
to switch?
It’s not the biggest part of the equation. Shorter sounds a bit tighter,
longer a bit fuller. We recommend picking what’s convenient to use.
Would PoE (Power Over Ethernet) provide a cleaner solution, soundwise and
aesthetically?
Unfortunately, no, most likely due to the buck boost converters those use.
Perhaps if we specifically design a PoE injector or a 54V powersupply but I
don’t think that’s the best way to go.
Why not include the AP directly inside the router, with an external
antenna?
If we can get good performance from that then we most certainly will do that
as a dedicated “audio” AP is absolutely better than routing your home hifi
through the router.
Would adding an antenna require making a new version of the router?
No, the Router has 2 m.2 PCIe slots on board. Adding a cutout for an
antenna is no problem.
There seems to be a SIM card slot on the left side of the board?
That slot is indeed for a SIM card, good to have options.
A 4G SIM in the Router’s SIM slot could allow for 100% isolation from the
home network. Is this an option?
Today, you could use any “low-powered” LTE/4G router (with modem build in) and
connect to the Extreme router to obtain the same advantage of isolation from
the home network. LTE/4G router – Extreme router – – switch – – server. This
has been tested some time ago but the router already provides ample isolation
from your home network.
Has a decision been made regarding the integration of an AP into the router
in order to have an all-in-one solution?
This is in the works.
Wifi to be added to the Router (updated implementation 25-05-2023)
We have integrated Wi-Fi working on the routers! This does require a PCB
change to work well which we are now considering to do for 2 reasons. The
first one being guaranteed SQ performance, and yes this is the solution which
produces superior results, the second reason is reduced complexity of setup,
in fact it can be virtually as easy to install as the switch, and easier than
the switch/network card bundle.
The downside is the increased BOM (Bill Of Materials), and we already forgot
to include a few items in that meaning we will have to increase the Router
price, likely to at least EURO 6600 and possibly a bit more. But of course, we
will honor the EURO 6000 presale price and those who placed presale orders
will get the wi-fi update for free.
Does this separate wifi network sound better than if I used port forwarding
and stayed connected to my main network?
Yes, it does.
Can the wi-fi feature in the future router be disabled?
Yes, it can be removed entirely.
Will you also issue a Router without wifi?
the Extreme Router will only be issued in its definitive form, which is with
wifi access point included. Alas, we will not make the earlier incarnation
available to the public.
There was talk of Router Subscription/maintenance cost?
We switched to openwrt, no maintenance cost.
Why not combine Switch and Router in a single chassis?
The thing is EMI/RFI is airborne inside the chassis and can couple back into
the circuit, of course you could create 2 internal chambers, but this would
both be about the same size / weight and actually a bit more expensive,
especially for post treatment / finishing and a higher change of transport
damage, especially since customs appears to like to unpack these frequently to
check what that massive blob is showing up on their Xrays.
In case of Extreme sever + Merging NADAC setup via Merging ASIO plugin and
an Extreme Network Card, where should the new Extreme Router be inserted?
The Router should be “in front of” the Extreme, like so: Router -> Extreme ->
Switch -> Nadac
Will the router ap be Cat6 or Cat6e?
As things are looking now, neither. We have the following setup running which
adds Wi-Fi over USB at a very low power consumption.
We could integrate this inside the Router chassis, ideally adding an exclusive
power rail/filter/regulator. This is by far the best solution we’ve tested.
We’re currently looking at what that would entail and if we can make this work
for the presale batch since it requires ordering new PCBs (although we can
recycle most of the expensive parts).
It looks like we can ship end of July with new PCBs. Wi-Fi would then be
integrated into the Router chassis and management interface. The SQ impact of
this Wi-Fi solution is virtually undetectable.
Will the router wifi work with Android?
Yes
If I don’t listen to streaming, I can leave the taiko router unplugged from
the main one, right? Will there be any benefit (sonically) to that?
You could but we feel it’s not worth the hassle.
Is the reason why the router uses ARM 16 cores because the better the
performance, the better the sound?
CPU performance matters but there’s more to it than just that. Somewhat
obvious is you want low utilization so performance is minimally impacted by
WAN side traffic and traffic rules processing like port forwarding. But
there’s more which went into the design of the router including the processor
selection which I’m afraid I cannot disclose to avoid being prematurely
copied. Prematurely being before we hit break-even on our R&D costs which
might be like a year away. Disclosing this aspect of the design would take
away most of the mystery surrounding the effects of ethernet networking so I’d
really like to share, but in the end, we do have a business to run and have to
keep netting positive. I hope you understand.
What is the optimal configuration?
RJ45 ethernet cable from home router to Taiko router and DAC cable from Taiko
router to switch is optimal. Further improved performance can be obtained by
powering both Taiko router and switch from a single DC power supply using the
Taiko DC distributor. Then there’s even more to be gained by using the
upcoming battery supply.
Is there any benefit in using SFP+ over SFP cable?
SFP = 1G
SFP+ = 10G
We supply SFP+. We did not compare the two but the expectation is that they
will perform the same.
What is the master clock frequency of the Taiko router and switch?
25MHz.
Since routers and Access Points generate noise, polluting our home
electrical grid network no matter how many audiophile routers/switches we use
for our hi-fi system, I wonder if you could share some configurations or
experience that can reduce this type of interference.
Unfortunately, we cannot provide fixed recommendations as this highly varies between routers, environment, and connected devices. In general, modern routers automatically adjust parameters while they attempt to provide good quality connections to all devices. They can for example automatically increase transmission power to increase the connection quality to a distant device which can in turn can generate more noise. So, the situation could occur where 2 APs with good combined coverage sum to less noise than a single one struggling to maintain good quality connections.
Why is there no power indicator LED on the Router?
Alas, we cannot add a power LED or a network status LED to the Router because
they negatively affect the noise spectrum and the shielding.
Can you recommend a router for the general home network? It is my
understanding you still need a main network router from which the Taiko router
will get its data.
Fritzbox has great routers. At taiko HQ, we use a Unifi dream machine pro and
are satisfied with that, but this has no integrated wifi. Unifi also has
cheaper models with integrated wifi.
Have you found that running Qobuz was better on a different DNS than
comcast (75.75.75.75)? Some members on WBF are also mentioning improved sound
with certain modems. The intent is to maximize the sound quality through
streaming.
The router really creates an isolated secondary network where all parameters
are controlled by it. We have not managed to find any meaningful differences
with preceding equipment, modems, routers etc. However, they can still
“pollute” your mains over their power supplies which is not something we can
solve.
Wifi Antenna Experiments
We’re currently experimenting with different antennas with some interesting
results. Where conventional audiophile “wisdom” would have you think a smaller
antenna is better, that is in fact not necessarily true, as what happens is
that a smaller antenna may need more transmitter power which in turn increases
noise. The same really goes for 2.4G vs 5G Wi-Fi, 5G needs more transmitter
power due to its shorter range which is most likely the actual cause of the
notion that 5G is bad for SQ. Evidence currently points towards SQ being
mainly impacted by a combination of antenna to device connection quality and
the transmitter power this requires. We’re going to optimize this for optimal
in room performance.
What about antenna size and signal strength?
I don’t know much about the subject, but shouldn’t the antenna be a fraction
of the wavelength (1/2, 1/4, etc.)? The wavelength corresponding to 2.4 Ghz is
roughly 12 cm, which would give antennas of 6, 3, 2 cm. And so on. There also
seems to be a relation between antenna length and directivity, not to mention
impedance. In short, I can imagine that it won’t be easy to choose, as all
this will ultimately have an impact on sound. It’ll be interesting to hear how
you arrived at your final choice. Purely by listening or/and on more practical
criteria?
The antenna will be very low power as it now consumes less power than a single
RJ45 network port. We expect minimal differences as the radio transmitter
power is set to manual and there will be only one Wi-Fi device. But we’ll see!
Did you try a non-omni directional antenna, like a beam antenna?
We have a few tests left to perform, but yes clearly there is some directivity involved.
Have you evaluated any sound quality difference between the F connector and
a BNC connector?
We did not try BNC and should add that due to this particular Wi-Fi solution
being virtually inaudible already, especially when able to stick to the lowest
possible transmission power, might make discerning differences in connectors
used near impossible.
Wifi versus Wired or Cable versus Wireless
We have come to believe that there will not be a general consensus because of
differing sensitivities to different types of noise and/or noise bands an
individual may have, and to complicate this further, the sensitivity of their
system setup and components to this. Another aspect related to Wi-Fi is we
don’t allow the transmitter to automatically increase transmission power.
Are jitter and latency a result of, or related to, power consumption?
Although lower latency equipment can use more power, we believe there is no
real correlation.
Processor Selection
or military grade hardware is something (ab)used in Hi-Fi to create an aura of
specialty so we are hesitant to use this kind of terminology, but we do use a
military grade security processor. The reason for this is this type of
processor is security hardened to an excessive degree, you may or may not be
aware that DATA can be stolen / reconstructed by measuring fluctuations in
processor / data line emissions and power draw. The processor & subsystem we
use has constant emissions and power draw, no fluctuations. This is the
highest obtainable security standard, which we arguably not need, but the
constant power draw and emissions are excellent for audio. This means that
data transmission does not translate into altering EMI and/or powerline
disturbances. This very likely changes the expected outcome of parameter
influences on sound quality relative to network gear which lacks this type of
extreme security hardening.
Is Airplay functionality support via the Taiko router still on the cards?
Yes, but further down the road.
