DESCRIPTION
The PSU-1250 and the PSU-1000 are the super inductive external power supplies dedicated to the Gold Note 1000 Series. Engineered with the best quality audio-grade components to provide our electronics, such as the CD-1000, DS-1000, PH1000 and the P-1000, with a large amount of ultra-clean power. For the PSU-1250 and the PSU-1000, we engineered a sophisticated design powered by a double inductor driving the negative and positive high-current stages, and with an inductive filter on the analogue stage
The PSU-1250 features a 7-Transformer design, with 4 transformers dedicated exclusively to the power supply stage, of which one for the galvanic insulation of the audio stage, and 3 dedicated to the Dual Choke Inductive Filter.
The PSU-1000 is powered by a 5-Transformers design, leveraging 4 transformers for the power supply stage and galvanic insulation and one for the Dual Choke Inductive Filter.
Our external power supplies perfectly filter the AC current and remove interference and electrical noise from the power system, allowing our electronics to perform at the best. Most importantly, they ensure the electronics always receive the optimal amount of power without generating EMI (ElectroMagnetic Interference) nor RFI (Radio-Frequency Interference) that could affect the audio signal due to electromagnetic induction, electrostatic coupling, or conduction.
With the PSU-1250 and PSU-1000, your system will deliver greater dynamics, better resolution and finer details for improved realism all-around and a higher level of musicality.
