PS Audio PMG Signature Phono Stage

PS Audio PMG Signature Phono Stage

The PMG Signature Phono Preamplifier is a groundbreaking leap into the future of analog playback—unlike anything any vinyl lover has ever heard. Designed from the ground up by PS Audio engineer Darren Myers, this revolutionary phono stage features a cutting-edge transimpedance input and a zero-feedback topology that strips away distortion, coloration, and noise, revealing the purest truth hidden in the grooves. It’s the first phono preamp in our 50-year history to bear the name of our founder—because it had to be that good. With dual inputs for both moving coil and moving magnet cartridges, and remote-controlled loading and gain options, the PMG Signature adapts effortlessly to any system. Its fully discrete FET design delivers massive headroom, ultra-low noise, and explosive dynamics that bring your records to life in ways you’ve never imagined. This is not just a phono preamp—it’s a liberation of analog. Vinyl, like you’ve never heard it.

Design

Phono preamplifiers—even at the highest levels—are often compromised by cost-cutting decisions: integrated circuits, shared power supplies, limited headroom, and simplified signal paths. The PMG Signature Phono Preamplifier throws all of that out the window. From the beginning, this was a no-compromise design, built with a singular goal: to create the finest phono stage in the world, regardless of price.

There’s not a single op-amp or integrated circuit in the signal path. Instead, every stage is constructed from hand-selected, discrete FETs and BJTs, operating in pure Class A. The topology is fully complementary and direct-coupled—chosen not for cost, but for its ability to deliver the lowest distortion, the highest resolution, and a complete absence of sonic fingerprint. The result is astonishing headroom, ultra-low noise, and lightning-fast transient response, capable of reproducing the most delicate nuances and the most explosive dynamics with equal ease.

While not inexpensive, the PMG Signature Phono Preamplifier is built to stand the test of time and stands head and shoulders above anything else we—or anyone—have ever built. If you're ready to hear just how far vinyl playback can truly go, you're ready for the PMG Signature.

Application

The PMG Signature Phono Preamplifier is the ultimate companion to the finest tonearms, cartridges, and turntables in the world. Designed as a true reference component, it redefines what’s possible in analog playback—delivering unmatched transparency, explosive dynamics, and a vanishingly low noise floor. Whether you're using a low-output moving coil or a high-output moving magnet cartridge, the PMG Signature brings out the full character of your setup with effortlessness and authority.

Its revolutionary transimpedance input gives cartridges a direct, uncolored path to amplification, eliminating loading concerns and revealing detail, texture, and space that conventional designs leave behind. For a more traditional approach, the voltage input offers adjustable gain and loading, all controlled remotely—so you can fine-tune your system from the listening chair.

With dual inputs for two tonearms, fully discrete zero-feedback circuitry, and precision control at every stage, the PMG Signature is not just another phono preamp—it’s the current state of the art, regardless of price. Use it in the highest-end analog systems on the planet and experience what’s been hiding in your vinyl all along. This is a revolution in analog performance.

Technology

PS Audio’s very first product in 1975 was a phono preamplifier that helped launch the company—and a movement toward better sound. Now, after 50 years of relentless innovation, we return to our roots with something truly extraordinary: the PMG Signature Phono Preamplifier. Designed by Darren Myers and bearing the name of our founder for the first time, this phono stage is unlike anything we—or anyone—have ever created.

At its heart is a groundbreaking zero-feedback architecture, a first in PS Audio’s history. This unique topology allows for something remarkable: the true separation of vinyl surface noise from the music itself. Once you hear it, you can’t unhear it—and you’ll never go back. Surface noise floats in the background, untethered from the performance, leaving the music alive, present, and shockingly real.

Adding to its revolutionary nature is an optional pure current-mode transimpedance input, ideal for low-output moving coil cartridges. This input requires no cartridge loading, offers unmatched transparency, and opens a window into your records that traditional voltage-input designs simply can’t match.

With fully discrete Class A FET circuitry, massive headroom, and support for all cartridge types, the PMG Signature Phono Preamplifier is a triumph of analog engineering—and the finest phono stage we’ve built in our 50-year history. From the first needle drop, you’ll know: this is vinyl reborn.
