The M1200 Amplifier is a formidable monoblock power amplifier from PS Audio, built with staggering output power and an extraordinary damping factor. The M1200 Amplifier represents PS Audio's most ambitious current statement in monoblock power amplifier engineering.
Key specs that matter
Input impedance is 100,000 ohms balanced or 50,000 ohms single-ended. Output impedance is a remarkably low under 0.007 ohms. Output power is a substantial 600W into 8 ohms, rising to a staggering 1,200W into 4 ohms. Gain is 30.5dBu. Frequency response spans 10Hz to 45,000Hz within plus-or-minus 3dB. Signal-to-noise ratio exceeds 112dB, with total harmonic distortion plus noise under 0.01% at 100% global feedback. Damping factor exceeds an extraordinary 1,100 - a remarkable figure indicating exceptional control over loudspeaker cone motion. At 432 x 305 x 95mm and 12.2kg, the M1200 Amplifier represents PS Audio's absolute current flagship monoblock engineering ambition.
Sound and use context
Expect extraordinary dynamic authority and control reflecting the extraordinary 1,100 damping factor combined with the staggering 1,200W-into-4-ohms output, representing PS Audio's most accomplished current monoblock engineering.
Pairing
As a monoblock, two units are needed for a stereo pair, and the extraordinary damping factor handles the most demanding loudspeaker loads.
Alternatives
PS Audio's own BHK Mono 300 and 600 offer related hybrid tube-and-solid-state monoblock alternatives within the same broader catalogue.
