Gold Note PSU 5 The Gold Note PSU-5 external power supply is dedicated to the PH-5 phono stage. If you are looking for a way to upgrade the performance of your Gold Note analogue system and get the best possible sound from your vinyl records, then the PSU-5 is an ideal solution. The PSU-5 features a 2-transformer circuit for the linear power supply stage in order to effectively provide the best working condition to the PH-5, with plenty of ultra-clean power. This allows the PSU-5 to prevent noise from the AC, which is also further removed by the dual-choke inductive filter developed with a dedicated transformer completely shielding the PH-5. The large and ultra-clean power generated also enables greater dynamic and finer audio details, guaranteeing the best realism and stage reconstruction.
