PS Audio Debuts Its New Top-of-the Line PMG Signature Series Audio Components

Boulder, Colorado, April 17, 2025 – In probably the most important product introduction in its 50-year historical past, PS Audio publicizes its all-new PMG Signature Series of top-of-the-line ultimate-performance audio parts. The 4 fashions within the collection embrace the PMG Signature Preamplifier, PMG Signature 512 PureStream DAC, PMG Signature Phono Preamplifier and PMG Signature SACD Transport. All are designed from the bottom as much as provide spectacular new ranges of efficiency and musical realism.

“These parts aren’t merely an evolution; they’re a design and engineering revolution, created to transcend listeners’ expectations in each approach possible,” famous Paul McGowan, PS Audio CEO.

PMG Signature parts function a surprising new look, with 1-1/2-inch thick machined aluminum entrance panels accented by a sweeping curved design. The entrance panel indicators are additionally touch-sensitive controllers, providing rapid management of all capabilities from an intuitive menu system. All PMG Signature fashions may also be operated by a newly-designed distant. Available in silver or black, the chassis have a sublime textured end that enhances any system and residing atmosphere. All fashions function a chassis-within-a-chassis design for max isolation, premium inside elements, multi-layer circuit boards, and different refinements.

PMG Signature Preamplifier

The Paul McGowan Signature Preamplifier is PS Audio’s new flagship. With a vanishingly low noise and distortion flooring of -150dB, the preamplifier uncovers musical reality with explosive dynamics, infinite depth, and holographic imaging. Designed by acclaimed engineer Darren Myers, it’s absolutely balanced from enter to output.

At its coronary heart is a revolutionary energy provide that eliminates conventional electrolytic capacitors, changing them with long-life, sonically superior movie capacitors. The outcomes are lightning-fast transient response, deeper silence, and better dynamic swings. It’s housed in a double chassis development that shields towards noise and interference.

The PMG Signature Preamplifier incorporates a totally reimagined achieve stage. The design blends FET (discipline impact transistor) and BJT (bipolar junction transistor) applied sciences, combining the finesse and linearity of FETs with the dynamic management and drive of BJTs. Fully complementary from enter to output, the achieve stage operates in pure Class A, direct-coupled and servo-controlled for absolute sign integrity.

What units this circuit aside is its progressive tackle folded cascode topology. Traditional cascodes use stacked transistors to enhance achieve and bandwidth, however the folded model “bends” the sign path, permitting excessive voltage swings, low noise, and broad bandwidth with out the instability or harshness of standard designs.

PMG Signature 512 DAC

At the core of the PMG Signature 512 DAC is the brand new PureStream DSD512 engine, changing any type of digital audio right into a pure 8X-DSD stream – there aren’t any PCM circuitry, no decimation filters, and no engineering compromises. The 8X-DSD stream feeds a newly-designed SpectraWave 64-tap sequencer, a digital filter that lowers noise and distortion whereas completely time-aligning the sign. From there, it flows right into a state-of-the-art, direct-coupled analog output stage. This is a radical departure not solely from conventional PCM-based architectures but in addition from standard DSD implementations and off-the-shelf chip options.

The PMG Signature 512 incorporates PS Audio’s famend Digital Lens know-how, making certain that incoming digital knowledge is completely reorganized and re-clocked earlier than ever reaching the PureStream engine. With a fully-balanced, direct-coupled analog output stage, galvanically remoted inputs, a built-in high-performance music streamer, and precision analog quantity management, the PMG Signature 512 isn’t just a DAC; it could actually function the centerpiece of a no-compromise reference system.

PMG Signature Phono Preamplifier

The PMG Signature Phono Preamplifier was designed from the bottom up by Darren Myers. It incorporates a cutting-edge transimpedance enter and a zero-feedback topology that strips away distortion, coloration, and noise. With twin inputs for each transferring coil and transferring magnet cartridges, and remote-controlled loading and achieve choices, the PMG Signature Phono Preamplifier adapts effortlessly to any system.

Its fully-discrete FET design delivers huge headroom, ultra-low noise, and explosive dynamics. From the start, this was going to be a no-compromise design. There’s not a single op-amp or built-in circuit within the sign path. Instead, each stage is constructed from hand-selected, discrete FETs and BJTs, working in pure Class A.

The topology is absolutely complementary and direct-coupled – chosen not for value issues, however for its means to ship the bottom distortion, the best decision, and a whole absence of a sonic fingerprint. The result’s astonishing headroom, ultra-low noise, and lightning-fast transient response, able to reproducing probably the most delicate nuances and probably the most explosive dynamics with equal ease.

The Signature Phono Preamplifier’s transimpedance enter provides cartridges a direct, uncolored path to amplification, eliminating loading considerations and revealing unmatched element, texture, and area. For a extra conventional strategy, the voltage enter presents adjustable achieve and loading, all managed remotely.

At the guts of PMG Signature Phono Preamplifier lies a daring and uncompromising design choice: the entire elimination of world suggestions. Using high-voltage discrete FETs and hand-selected bipolar transistors in a completely complementary topology, this phono preamp achieves one thing few engineers have dared try – a real zero-feedback phono stage with vanishingly low noise and distortion.

PMG Signature SACD Transport

The PMG Signature SACD Transport connects a DAC to the hidden magic of pure DSD that’s been locked away in SACD discs. This isn’t simply one other disc participant; it’s the best optical disc transport PS Audio has inbuilt 43 years.

With galvanically remoted outputs and an ultra-low jitter design, it breathes new life right into a CD assortment when paired with any DAC. When related by way of I²S, it unlocks the uncooked DSD layer of SACDs, delivering what was as soon as hidden to exterior DACs.

New to this mannequin, and for that matter, any disc participant ever made, is the inclusion of PS Audio’s galvanically remoted output stage. By coupling the output of the drive mechanism to the transport’s inside Digital Lens by a pulse of power throughout area, any hints of noise or floor contamination are eradicated. The outcomes of this whole digital isolation is a beforehand unheard stage of picture separation, openness, and easy replica. Musical particulars that had been as soon as buried beneath noise and jitter are lastly free to come back to life.

PS Audio PMG Signature parts might be obtainable at a advised US retail worth of $8,499 every. Delivery might be within the third quarter of 2025.
