The PSU-10 is a super inductive & chokes power supply designed exclusively for the PH-10 phono stage. PSU-10 has been engineered with the best quality audio-grade components to enhance the performance of PH-10 and improve even further your system: with the dedicated external power supply you will get the very best music experience out of your LPs. For PSU-10 we have chosen a dual choke design powered by a double inductor driving the negative and positive high current stages and featuring and inductive filter on the analogue stage. The Gold Note proprietary Dual Chokes Design perfectly filters the signal voltages in order to eliminate all the possible electrical pollution coming from the AC power system. The PSU-10 uses its massive power supply to shield the PH-10 phono stage from electro-magnetic interferences thus insulating it effectively from the AC power system. The large, ultra-clean power enhances super low noise, greater dynamic, better resolution and finer details for a more realistic high-end audio performance and pure audio pleasure. The PSU-10 can deliver high quality power using 4 transformers 3 of which are dedicated exclusively to the pure power supply and with 1 separated transformer dedicated to the inductive filter.
