Contact for purchase and more info (black only) The PSU-10 external power supply is designed to improve the performance of the Gold Note PH-10 pre-phono, thanks to its hybrid Super Inductive Dual Choke technology. It is characterized by an inductive filter on the analogue stage and is powered by a double inductor that drives the high current stages both negative and positive. This proprietary technology is able to perfectly filter the signal voltage to eliminate any interference and electrical noise from the AC power system, achieving complete isolation and creating an ideal environment for the PH-10 phono stage to perform at its best. The power and cleanliness of sound generated by PSU-10 allow for reduced interference, ensure better dynamics and resolution, restore the smallest sound details and reproduce the musical event in an extremely realistic way. Dedicated to the pre-phono PH-10, the PSU-10 power supply has 4 power stages with 4 very low noise voltage regulators. The device is powered by 4 transformers, 3 of which are dedicated to the power supply and 1 to the special dual choke inductive filter. The PH-10 must be updated with the latest firmware to be compatible with the PSU-10 power supply; to know how to update your PH-10 consult the Download area of the website.
