PS Audio has made a range of high grade, decent value products under the "Stellar" moniker for many years now. Here we have the ultimate Stellar Mono Block amplifiers - these 600w (8 ohm) beasts meld the power, bass control and efficiency of class D with class A tube warmth and musicality.
We have used these amplifiers on all srts of speakers from bookshelf style to KEF Blade 2 - and the M1200 amplifiers always give the impression of open, detailed soundstage with limitless dynamics.
PS Audio’s new Stellar M1200 began as a “dream project" of PS Audio engineer Darren Myers. Darren wanted to see what would happen if he combined one of the world’s highest power amplifier stages with a rich and warm vacuum tube input stage.
The result? A monoblock power amplifier that marries a Class A vacuum tube (12AU7) input stage with a Class D output stage capable of delivering 600 watts (into 8ohms) or 1200 watts (into 4 ohms). Each 12kg block features RCA and balanced XLR inputs, a 3.5mm trigger input, and solid copper-plated output binding posts.
Remember, power amplifiers deliver only the number of watts required by your speaker to achieve the desired loudness. Even the most powerful amplifiers deliver only what’s asked of them. What’s been missing in most amplifiers is adequate headroom and effortless linear performance—something only a vacuum tube-based powerhouse like the M1200 can unquestionably provide. From the most subtle of details to unheard of explosive dynamics, Stellar M1200 represents the pinnacle of high powered musicality that must be heard to be believed. Regardless of the power demands—or power limitations—of your loudspeakers, Stellar M1200 is the perfect choice if effortless musicality is in your future.
