PSU-1000
Dual-Choke Linear PSU — Unlock Full 1000-Series Performance
Descripción ⌄
GoldNote PSU-1000 — external linear power supply. External linear power supply for Gold Note 1000-series components (PH-1000, P-1000 mkII, CD-1000 mkII) with dual choke inductive filtering and ultra-low-noise voltage regulation. Noise rejection exceeds 80dB with 0.05% output voltage stability and full-power response under 2.5 microseconds. Significantly enhances dynamics and resolution of the connected component.
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.
