PSU-1250 are the super inductive external power supplies dedicated to the 1000 Gold Note series, such as CD-1000 MkII, P-1000 MkII and PH-1000. Both PSU-1250 and PSU-1000 are the result of a sophisticated design with an inductive filter on the analog stage and power supply via a double inductor for the positive and negative stage. PSU-1250 has a configuration of 7 transformers, of which 4 are dedicated exclusively to the power stage, with a transformer for the galvanic isolation of the audio stage and 3 to the Dual Choke inductive filter.

PSU-1000 is instead powered by a 5 transformer configuration, 4 for power and galvanic isolation and one for the Dual Choke inductive filter. These external power supplies perfectly filter the electrical signal eliminating possible interference and disturbances so as to allow our electronics to express the sonic characteristics at their best. PSU-1250 and PSU-1000 provide ultra-clean power and all the necessary power without generating Electro Magnetic Interference or Radio-Frequency Interference that could affect the audio signal. All this translates into greater dynamics, better resolution, precise details and maximum realism.
