Design
The Paul McGowan Signature Preamplifier is a bold leap beyond anything that’s come before. Its fully balanced circuitry delivers an unprecedented level of purity and control. With a dynamic range approaching 150dB—the difference between a single molecule of sound and standing beside a roaring jet engine—it achieves a level of sonic blackness almost no other design on Earth can touch.
Transients explode with lightning speed, and its bandwidth stretches beyond 500kHz for limitless openness and realism. High-speed, zero-feedback Diamond buffers preserve every musical nuance, while a revolutionary film-capacitor power supply unleashes dynamics with astonishing grace. This is not refinement. This is reinvention. The PMG Signature is pure musical authority.
Application
The preamplifier is the heart of any high-end system. Every note, every breath, every bit of music from your sources—DACs, phono stages, CD players—passes through it before reaching your power amp. It’s the final gatekeeper, and it better be right.
The Paul McGowan Signature Preamplifier is the first product in 50 years to carry my name, and for good reason. It delivers complete control, ultra-low distortion, and total isolation between sources and amplification. With five identical balanced and single-ended inputs, all signals are converted to fully balanced and passed through our zero-feedback Class A Diamond buffers. Nothing is added, nothing taken away.
This is where the magic happens.
Technology
The Paul McGowan Signature Preamplifier is a statement of what’s possible when nothing is held back. Designed by Darren Myers and carrying the name of our founder for the first time in 50 years, this is the culmination of a lifetime of innovation. Fully balanced from input to output, every stage features zero-feedback Diamond buffers for unmatched speed, transparency, and control. A high-resolution stepped attenuator ensures precise volume with 1/10th dB channel accuracy, revealing microdynamics with lifelike precision.
At its heart is a revolutionary power supply that eliminates traditional electrolytic capacitors, replacing them with long-life, sonically superior film capacitors. The result is lightning-fast transient response, deeper silence, and greater dynamic swing. Housed in a double chassis construction that shields against noise and interference, the PMG Signature achieves a noise floor of -145dB—so quiet it’s not there.
What you hear is exactly what was recorded—nothing added, nothing taken away. No glare, no grain, no veil. Just the music, uncolored and alive. The PMG Signature is the finest preamplifier we have ever built.

PS Audio – Airlens Network Music Streamer
The AirLens™ interface brings perfection to streaming
Streaming audio via Roon or other services like Qobuz, Tidal, and Spotify offers millions of titles at the touch of a finger. Unfortunately, connecting your sensitive DAC to the noise generated by computers, routers, NAS, local networks, and modems via either WiFi or Ethernet cable is not a great-sounding solution to bringing high-performance audio into your listening environment. The PS Audio AirLens™ completely eliminates the problems of noise, jitter, and EMI influences through complete galvanic isolation and perfect reclocking of the digital audio signal. You’ve not yet heard how great streaming can sound until you experience audio through the AirLens.
