PS Audio Stellar M1200 Mono Power Amplifiers

PS Audio Stellar M1200 mono power amplifier provides an unmatched level of control, dynamics and power and is rated at 600 watts into 8 ohms and 1200 watts into 4 ohms. The Class-A vacuum input stage provides an uncompromised level of musicality and sonic character with zero feedback.

Breath-taking Musicality

The M1200 mono power amplifier is designed to handle any size loudspeakers no matter what sensitivity. It produces exceptional musical power and dynamics without limitations, unlike a lot of power amplifiers that are unable to perform out of their comfort zone. With the M1200 a new level of musicality is unlocked and the most delicate musical details and complex passages are absolutely preserved.

Class-A Vacuum Input stage

The M1200 does not lose any of the soundstage width, instrumental tones, subtle cues, or depth that can often be lost with power amplifiers. Meticulously designed by PS Audio’s Darren Myers to capture even the tiniest musical nuances, the M1200 incorporates a zero feedback class A vacuum tube input stage.

The result? An incomparably dynamic performance that captures every essence of each musical piece ensuring the finest details are preserved for a rich and expansive listening experience.

Class D Output Stage

By taking a hybrid approach and merging the vacuum tube input with a class D output stage this amplifier is able to efficiently transfer low loss music to your speakers. The Stellar M1200 provides a massive amount of power, delivering a maximum of 1200 watts into 4 ohms. It has excellent damping properties, high efficiency, low distortion and delivers an exceptional frequency response.
