Power Amplifiers
Engineered to a standard you can hear: natural timbre, low noise, low feedback.
New to separates? A power amplifier is the muscle of your system. It takes the small signal from your preamp or source and gives your loudspeakers the power they need to fill the room with music.
The family runs from our reference PMG Signature monoblocks and stereo amplifiers to the accessible Stellar M700, S300, and M1200 — plus the Stellar Strata MK2 integrated if you'd like DAC, preamp, phono, and amplification in one tidy chassis. Whichever you choose, the promise is the same: your speakers disappear, and the magic of music fills your home.
Every PMG Signature amplifier shares one topology — designed by Darren Myers, engineered by Bob Stadtherr — with an active power supply and generous Class A bias that keeps your music in the amplifier's sweetest, most linear region. Stellar models bring that high-current performance within easy reach. Low feedback and bandwidth beyond 500 kHz aren't just numbers we're proud of; they're the reason the amplifier steps out of the way and lets the music through.
This is the PS Audio power amplifier family — from reference PMG Signature to accessible Stellar. Hand built in Boulder, Colorado, by people who can't wait for you to hear it, and engineered to bring music to life in your home.
