Ground-breaking technology, uncompromising precision, flawless execution
We can assert with confidence that at the present time, the SD-025 represents the ultimate in DAC/streaming. Based on the time honoured Vitus Audio principle of ‘building on giants’, the device takes a significant step upwards from the RD101. Its myriad components work together with a degree of harmony suggestive of the great artistes and ensembles whose music it is designed to replicate so faithfully. Indeed, the analogue output stage employs the same topology as our amplifiers and the resulting open loop bandwidth of 2.5MHz gives a very linear phase response, one of the key attributes of correct musical harmony. With its inherent finesse and authenticity the SD-025 has, at a stroke,raised the bar in advanced hi-fi technology, offering a phenomenal power supply as well as an optimised digital analogue circuit.
Audio Therapy’s reviewer asked: Is this the best one-box DAC in the world?
“The SD is endlessly detailed, hugely transparent, but it never sounds strident, aggressive or ‘digital’ in character, it’s tonally smooth and neutral. All of the details and dynamics are front and centre but they never force themselves upon you. They creep up and once they get under your skin, there really is no going back.”
Together, the DAC device and the separate sample rate converter module deliver a pristine sound that eradicates all distortion and extraneous noise. The listener enjoys an experience akin to being physically present in the concert hall.
The sample rate converter offers sample rates of up to 384 KHz/32 bits instead of the more common 192KHz, thus increasing the amount of available bandwidth. Consequently, we developed a Masterclock to support the conversion modules. This was an expensive refinement, but one that delivers a disproportionate enhancement in a sound quality evoking that of phono and reel-to-reel decks of the very highest calibre – soft, warm, and all-encompassing.
The larger, optimised power supply further helps to ensure that the digital audio signal is transformed into an unparalleled analogue equivalent.
Hence the listener enjoys an aesthetically and emotionally authentic
experience that captures both the overall creative intentionof the music and
the finest nuances of its performance. The built-in streamer supports all
common streaming services. It is controlled through the Mconnect Control app
with its intuitive interface
that makes it a real pleasure to stream musical favourites. Multiple devices
can even be connected across rooms through awired Internet connection or WiFi.
The SD-025 is part of Vitus Audio’s Signature Series where functionality and design are combined in a unique and durable premium product of outstanding quality – one that in 20 years will still be delivering musical experiences of the same towering quality as it does today.
