PST-10
External Turntable PSU — Eliminates Motor Speed Electrical Interference
Descripción ⌄
GoldNote PST-10 — external power supply with transformer isolation. External four-stage inductive power supply for Gold Note mid-range turntables (Mediterraneo, Giglio, Pianosa, Valore 425), featuring four audio-grade transformers and a 1.5m silver conductor cable. Delivers >80dB noise rejection, 0.05% output voltage stability and response time under 2.5 microseconds. 200×80×260mm chassis, 3kg; supplied standard with Bellagio turntables.
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
IS-10 owners wanting a precision AC power conditioner to reduce mains noise; System 10 users wanting to complete their mains conditioning setup GoldNote turntable owners in the Mediterraneo–Valore range wanting a motor PSU upgrade for enhanced speed stability Turntable upgrade: Mediterraneo or Giglio + PST-10 — recommended upgrade for improved bass control and dynamic range
