PSU-5

GoldNote PSU-5 — external power supply for PH-5 and smaller products. External dual-transformer linear power supply specifically for the PH-5 phono stage, with inductive dual-choke filtering and three ultra-low-noise voltage regulators. Delivers >80dB noise rejection, 0.05% output voltage stability and response time under 2.5 microseconds for enhanced vinyl reproduction. Compact 200×80×260mm chassis, just 2kg.

Technical background

GoldNote external power supplies use Super Inductive Dual Choke (SIDC) technology — dual inductor rails that reject common-mode and differential-mode interference simultaneously, achieving >80dB noise rejection. Ultra-low-noise voltage regulators maintain 0.05% output stability with full-power response under 2.5 microseconds, ensuring the connected component is never starved of current during dynamic peaks in the audio signal.

Design story

GoldNote's external PSU philosophy evolved from the discovery that the noise ceiling of their internal power supplies — while carefully designed — could be lowered by dedicated outboard units. The SIDC technology was developed in-house and refined over successive generations; the PSU-1250 now deploys seven independent transformers and regulators, achieving a noise floor that is effectively inaudible even on the most revealing phono stages and DACs in the GoldNote range.
