PSU-10 EVO
Four-Rail Dual Choke Hybrid PSU — System 10's Most Impactful Upgrade
Description ⌄
GoldNote PSU-10 Evo — external power supply for 10-series products. External four-rail audio-grade power supply for DS-10 Evo, DS-10 Evo Line, HP-10, CD-10 and CD-5 with Dual Choke Hybrid inductive filtering. Features four transformers, two ultra-low-noise voltage regulators and noise rejection >80dB with 0.05% voltage stability. Compact 200×80×260mm chassis, 4kg, dynamic power output over 100W.
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.
Best for
DS-10 Evo, IS-10, or PH-10 owners wanting a meaningful performance upgrade via dedicated outboard power supply; the single most cost-effective upgrade in the System 10 range DS-10 Evo, IS-10 or PH-10 owners wanting the most cost-effective performance upgrade; System 10 complete builders System 10 upgrade: DS-10 Evo + PSU-10 Evo — hi-fi+ Highly Commended combination for a significant leap in resolution
