  • Design

    The hybrid approach used in the Stellar M700 Power Amplifier takes advantage of the best traits technology has to offer. The perfected analog voltage is then converted into the high current output needed to effortlessly drive your loudspeakers.

  • Application

    The M700 is Stellar's best. Rated at 350 watts into 8Ω and 700 watts into 4Ω, a pair of these placed on any loudspeaker brings forth the lush, rich, and soul-satisfying power of two completely independent power blocks with headroom to spare. The listening experience with the M700 starts feet tapping and smiles breaking out. One listen to a hugely loud and complex musical passage effortlessly rendered by the M700 pair and you'll know you made the right choice.

    Technology

    Rated at 350 Watts into 8Ω and 700 Watts into 4Ω, the M700 combines the best of two worlds: ultra linear, high-current, Class D technology for the output stage; a discrete, Class A MOSFET based Analog Cell for the all-important input stage. The Stellar M700 captures the rich, full-bodied essence of recorded music and presents it to your loudspeakers with authority and grace, never a hint of glare or unnaturalness. The M700 is faithful to the music like few amplifiers are. Listeners are constantly surprised at the width and depth of the M700's soundstage; its preservation of the smallest details in reverb, room acoustics, and musical overtones; its commanding presence without intrusion; its delicate handling of subtle shadings; its authority as it grabs hold of the loudspeaker and breezes through even the most complex musical passages.

    They are a revelation!

    I have had the 700's for several months now and all I can say is..."WOW!" Even after the burn in period at PS Audio, that was not the end of the burn in process. It's taken a few more months and I don't even know now if they will continue to do this. However, I can't tell you enough of what these amps have done for me in terms of detail and no compression of sound in loud passages of music/film. For me, they are a revelation! It's only been in the last month or so that actors, orchestras, soloists have exited the speakers and are in my home theater room! The Maggies are so much more in richness and dynamics that I really can't believe it! I had a gut feeling prior to purchasing them that I was in for something very special and that's putting it mildly! I've received Paul's emails over the years and actually this was a blind purchase but the price was certainly right for each of the six amps and the trade in of my Carver 7 channel amp was financially sufficient enough that the value given me would cover one and a half of the 700's!

    Bravo!

    I just replaced my Parasound Halo A21 amp with your M700's. All of my electronics are now PS Audio: BHK pre, P5 power conditioner, memory player, Direct Stream DAC, and now the m700”s. Each new piece marked an improvement in my system. But the addition of the amp took my system into some place magical. When I read equipment reviews, I am often skeptical of the claims therein. I have to say that the level of musical engagement was so palpable as to defy belief. There was great clarity and even 3-dimensionality with the PArasound, but the M700's brought something else into the field. It is almost impossible for me to hear my music and not want to move with it. That is the way I feel at a club or a concert hall. Now it is in my living room. Every one of my friends who have heard my system as I have slowly built it has been impressed, but the final handshake between all your components is something beyond my explanation. Obviously, I am a fan, but there are times when you need to give praise for the efforts and dedication that you people bring to your products. Bravo!
