Сетевые фильтры и HiFi-мебель — Gold Note PSX-5.2

The PSX-5.2 is an external power supply from Florence-based Gold Note, designed exclusively for its Series 5.2 components. It evolves the earlier PSU-5 and can power two components at once, a phono stage and a line-level source. Gold Note presents it as a system-level upgrade rather than an accessory for one unit.

Key specs that matter

The PSX-5.2 has four audio-grade supply rails and two ultra-low-noise voltage regulators. Maximum output voltage variation is 0.05%. Line noise rejection and common-mode noise rejection both exceed 80 dB. Full power response time is below 2.5 microseconds. Power consumption is 40 W, dynamic power exceeds 60 W and standby draw is below 1 W. The mains input auto-senses 100 to 120 V and 220 to 240 V. The unit measures 200 x 80 x 260 mm and weighs 2 kg. UK pricing was GBP 700.

Engineering and use context

The dual-output architecture lets a phono stage, the PH-5 or PH-5.2, and a line source, such as the CD-5, CD-5.2, HP-5.2 headphone amplifier or DS-5.2 network player, stay connected at the same time. When one output is selected, the whole power reserve is dedicated to that component. Moving the supply out of each component takes the mains transformer and rectification away from sensitive analogue circuits, especially important for a phono stage amplifying signals of fractions of a millivolt. The fast response means the supply keeps up with transient current demands of the audio circuits, and the tight regulation keeps the voltage steady under load. High line and common-mode rejection block noise arriving from the mains. The chassis is black anodised aluminium with a sandblasted finish, matching the Series 5.2, and it is designed to limit interaction with external magnetic fields. The PSX-5.2 lets owners improve a Gold Note system step by step without replacing components. Shipped weight is 3 kg, the mains fuse is a 2 A time-delay type, and the unit sells in Europe for EUR 720 as an optional upgrade to any Series 5.2 component. Gold Note designs and builds the unit in Montespertoli, in the hills outside Florence. The PSU-5, its predecessor, used a two-transformer linear design with a dual-choke inductive filter.

Pairing

The PSX-5.2 works only with Gold Note Series 5.2 components and the PH-5. A PH-5.2 phono stage and a CD-5.2 player can share one unit.

Alternatives

Gold Note's PSU-5 is the earlier external inductive supply for the PH-5 and PH-5.2 phono stages.
