PMG Signature 512 DAC

<strong>Meet the all new PMG Signature 512 DAC powered by PureStream DSD.</strong>

Digital audio was born in 1982 with the launch of the first CD player, and PS Audio didn’t miss a beat—we introduced the world’s first high-performance standalone D-to-A converter and never looked back.

Now, after decades of innovation, we proudly unveil the PMG Signature 512 DAC.

At its core is the PureStream DSD512 engine, converting any form of digital audio into a pure 8X DSD stream—no PCM, no decimation, no compromise. That stream feeds our SpectraWave 64-Tap Sequencer, lowering noise and distortion while perfectly time-aligning the signal. From there, it flows into a state-of-the-art, direct-coupled analog output stage.

The result is breathtaking—fluid, natural, and as analog as it gets. With a built-in high-end streamer for seamless access to your music, the 512 is our best DAC ever.

For the first time in PS Audio’s history, our founder’s name graces a DAC. Yes, it’s that good. And this time, it’s personal.

Design

Designing the PMG Signature 512 DAC was never about meeting expectations—it was about redefining what a digital source could be. This is a radical departure not only from traditional PCM-based architectures but also from conventional DSD implementations and off-the-shelf chip solutions. At its core is our all-new PureStream DSD512 engine, a proprietary design that upsamples every input—PCM or DSD—to a native 8X DSD stream. That stream is then refined by our SpectraWave 64-Tap Sequencer, a precision digital filter engineered to eliminate jitter, reduce noise, and preserve every nuance of the music. The result is pure sonic truth, passed into a fully balanced, direct-coupled analog output stage. With galvanically isolated inputs, a built-in high-performance streamer, and precision analog volume control, the PMG 512 is not just a DAC—it’s the heart of a no-compromise reference system.

Application

The PMG Signature 512 DAC is as versatile as it is revolutionary—and a major step above even the finest DACs we’ve ever built. Use it as a standalone directly into your power amplifier, thanks to its ultra-precise analog volume control, and experience purity, dynamics, and realism like never before. At its heart is PS Audio’s latest high-definition streaming module, fully galvanically isolated to eliminate noise and preserve absolute musical integrity. Whether paired with the PMG Signature Preamplifier for the ultimate reference system or run solo into your amp, the 512 delivers sound that is breathtakingly clear, natural, and alive. This isn’t just high-end performance. This is a whole new benchmark. The PMG Signature 512 DAC is music, uncompromised.

Overview

Think of the PMG Signature 512 DAC as the ultimate destination in digital audio—a no-compromise centerpiece for the most revealing high-performance systems. Whether your setup is purely digital or a hybrid of analog and digital sources, the 512 redefines what’s possible from a DAC. Built around our PureStream DSD512 engine and SpectraWave 64-Tap Sequencer, and featuring a fully balanced, direct-coupled analog output stage, the PMG 512 delivers sound with breathtaking realism, depth, and musicality. It supports I²S for a perfect connection to our top transport, and includes a world-class galvanically isolated streamer. Replace your DAC, your streamer—or even your preamplifier—and prepare to be stunned by the transformation. Rich. Pure. Effortless. The PMG Signature 512 DAC is the product of over fifty years of innovation and the first to carry the name of our founder. It’s not just the best DAC we’ve ever built—it’s the best DAC we know how to imagine.

PureStream DSD512 engine

At the heart of the PMG Signature 512 DAC is a breakthrough in digital audio: our PureStream DSD512 engine. Running at a blazing 22MHz, PureStream upsamples any incoming PCM or DSD signal to a native 8X DSD stream—far beyond standard formats and completely free from PCM conversion or decimation. This ultra-high-resolution DSD stream is then passed through our SpectraWave 64-Tap Sequencer, which time-aligns and refines the signal with surgical precision, lowering noise and distortion while preserving every musical nuance. From there, it flows directly into a simple, elegant analog low-pass filter—no complex conversion stages, just pure music.
The 512 doesn’t rely on off-the-shelf DAC chips. This is a custom-designed platform built from the ground up to achieve what no other DAC has: sonic transparency with SINAD better than -100dB and vanishingly low output noise. Multiple ultra-stable reclocking circuits, galvanic isolation between all digital inputs, and full separation between digital and analog sections ensure jitter-free, noise-immune performance.
And yes, the PMG Signature 512 also features our renowned Digital Lens technology, ensuring that incoming digital data is perfectly reorganized and reclocked before ever reaching the PureStream engine. Every effort in its design—from input to output—is focused on preserving imaging, tonal richness, and musical truth. One listen, and you’ll know: this is unlike anything you’ve heard before. The PMG Signature 512 DAC is not just a component—it’s a revolution in digital audio.

An inside look

The SpectraWave 64-Tap Sequencer is a groundbreaking solution within the PMG Signature 512 DAC, unlike anything used in traditional digital filters. Engineered as a fully discrete, patent-pending FIR architecture, SpectraWave operates at the same extreme 22MHz sample rate as our PureStream DSD512 engine. Designed from the ground up to handle ultra-high-speed data streams, its 64 precisely tuned taps work in real time to align musical transients with absolute accuracy, ensuring perfect phase coherence and eliminating timing smear.
Where typical filters introduce artifacts like pre-ringing or harmonic distortion, SpectraWave maintains the purity of the signal without compromise. It preserves the natural shape and timing of every note, creating a spacious, uncolored soundstage with lifelike presence. Instruments bloom into three-dimensional space. Transients arrive exactly when they should. Nothing is exaggerated. Nothing is lost.
Following the sequencer, the signal flows seamlessly into the PMG Signature’s fully balanced, direct-coupled analog output stage. This minimal-feedback circuit is designed for speed, transparency, and control. With ultra-low output impedance and high current drive, it effortlessly powers even the most demanding downstream components. There are no transformers, no coloration, and no filters to blur the truth—just a clean, open window into the soul of the music.
This isn’t just a better DAC. It’s a complete rethinking of what digital audio can be.

Whether I play poorly recorded music or really well recorded music, the musicality enhancement is quite real.

But the resolution that I am now able to hear without effort is more than mind-bending. You and your team have knocked this one out of the park! I am hearing acoustic environments and timbres that I was simply not aware of.

Jonathan

"I was awestruck. Stability, imaging, clarity, soundstage width and depth, silence between notes, dynamic range, bass reproduction, and "musicality" were consistently outstanding. I own a very good DAC -- the ****** Designs' M21. I would say the new PS Audio PMG DAC is at least its match and perhaps even its better. Bottom line: if you are in the market for a new DAC , you must seriously consider the PS Audio PMG DAC

Maybe flabbergasted is too strong a word to describe what I heard, but I think it’ll do. There are no nuances. Everything is obvious, and better, and not in a small way. Instruments are precisely placed, not only across the soundstage but also front-to-back. I didn’t realize my DSD was smearing the size and placement and the actual sound of the sound until I heard the same pieces via the PMG. It’s as though there was always cloud of chaff, but I never noticed it until it was gone.

Vocals on the PMG 512 were clearer, more defined in space, and even more natural and human in tone and presence. Cymbals were less smeared, more refined and delicate, the soundstage was wider and dimensional. Now, despite my old man hearing, I can hear more distinct, intelligible vocals. The background singers and instruments that I previously had strained to hear. It has been very rewarding listening to the new PMG series.

I am using the PMG dac without a preamp, couldn’t do that with the MKII. The upgrade is fantastic. Go with the dac.
