AudioStream, Rafe Arnott

All PS Audio components I’ve encountered (or owned) are incredibly well-built and the Stellar line is no exception. They have a weight, look and feel that exudes quality belying their sub-$5,000 USD total cost and puts me in mind of gear I’ve reviewed costing double this price point. READ MORE

Positive Feedback,  Pete Davey

I was really able to hear the amplifiers’ real attributes: astonishing and accurate bass, with sparkling highs that had an almost tube-like sound. How did they accomplish this in such a small footprint for such an amazing price? READ MORE

The Audio Beat, Guy Lemcoe

I could not fault the sound of the Gain Cell DAC -- its neutrality and honesty were captivating, leading to compelling listening. During my time with it and the pair of M700s, I always felt they had total control over whatever music was thrown at them, in whatever format. From the understated nuance of an unaccompanied lute to the bombast of a symphony orchestra going full tilt, the laid-back drive of dub or the pulse of electronica, I not once felt deprived of any of the music’s emotion, rhythm, dynamics or detail. Whether using planar, stand-mounted or floorstanding speakers, I knew... READ MORE

PS Audio has been on a roll. That roll continues with the Stellar M700 power amplifier. I have had nothing but good experience with PS Audio products; still, with the Stellar M700, my expectations were exceeded. Having little sound of its own, the M700 delivered well-balanced reproduction that was always faithful to the music… the Stellar M700s came ever so close to matching the sound of my high-end reference monoblocks, Theta Digital's Prometheuses—which are ranked Class A in "Recommended Components" and, at $12,000/pair, cost four times as much as the PS Audios. The Stellar M700 is an... READ MORE

Stereo Times,  Greg Voth

I’ve been putting source material through the rig with the PS Audio Stellar M700’s Mono amps for a month and I have been consistently impressed with their musicality and get up and go. These powerful PS Audio Stellar M700 Mono amplifiers are capable of effortlessly driving demanding loudspeaker loads to concert levels. This may be the first higher-priced component I can’t live with out... but wait, there’s more! At $2995 per pair, they’re not higher priced, just bit of a stretch for my thin wallet. If my 83 dB sensitive speakers have anything to say about it, these review amps have found a... READ MORE

Positive Feedback,  Gary L Beard

In the Stellar M700, PS Audio has designed excellent sounding mono amps that can be the foundation of a reasonably priced high-end audio system. The analog input section is as expansive and natural sounding as the ICE amp modules are powerful and accurate. The resulting sound is a wonderful balance between expression and precision, allowing the amps to disappear within the audio chain. They clearly take on the signal they are fed, allowing a great front end to weave its audio magic. READ MORE

SoundStage! Roger Kanno

There are many excellent-sounding amplifiers in this price range, but few can put out anywhere near as much power as the Stellar M700, and most of those that do don’t sound as refined. PS Audio says that the Stellar M700 is one of the most extraordinary monoblocks ever sold for less than $5000/pair. I have to agree. The Stellar M700 is my new favorite entry-level high-end power amplifier. READ MORE
