PS Audio PMG Signature Preamplifier Now Available

First revealed at AXPONA 2025 in April, the PMG is part of the all-new Signature Series—four reimagined components designed to replace the longstanding PerfectWave line.

The new preamplifier marks a significant milestone for PS Audio as it celebrates its 50th anniversary. It positions the Signature Series as a clean break from the past and a bold step forward in both design and performance.

Created by PS Audio’s Design Engineer, Darren Myers and named in honour of co-founder Paul McGowan, the PMG Preamplifier is a complete ground-up reinvention. Visually, it departs from the brand’s previous design language, introducing a curved, machined aluminium fascia, a responsive capacitive touchscreen, and a newly developed remote control.

Internally, it adopts a double-chassis architecture to separate power and control circuitry from the sensitive analogue signal path—an approach aimed at reducing electrical interference and improving sonic purity.

Beneath the striking exterior is a fully balanced signal path employing zero-feedback Diamond buffers operating in pure Class A. The gain stage features a hybrid topology that combines the finesse of FETs with the drive of BJTs, targeting high bandwidth, low distortion, and musical authority.

PS Audio has also chosen a film capacitor-based power supply instead of traditional electrolytics, a decision said to improve transient response, reduce noise, and enhance overall dynamic expression.

Input flexibility includes five balanced and single-ended analogue inputs, while a precision stepped attenuator offers 0.1 dB channel matching. The preamp’s bandwidth extends well beyond 500 kHz, with the company claiming a distortion and noise floor approaching –145 to –150 dB.

Despite the lab-grade specifications, PS Audio is quick to downplay the numbers in favour of the listening experience. Myers explained at launch of the  all-new Signature Series: 

We didn’t want to build a lab instrument, we wanted to build something that lives and breathes with the music.

The PMG Signature Preamplifier is available now with a suggested retail price of US$8,499 | A$15,990 | £8,995 | €9,995.
