PS Audio Stellar M700 monoblock power amplifier test review

Robert Deutsch / Stereophile write:

Although PS Audio's Stellar M700 monoblock power amplifier ($2998/pair) is a brand-new design from a team led by engineer Darren Myers, it draws on the company's extensive experience with class-D amplification. Sam Tellig and Kalman Rubinson reviewed PSA's HCA-2 power amp in, respectively, the October and December 2002 issues, and I reviewed their GCC-100 integrated amp in January 2006. The Stellar M700's input stage is the latest version of PS Audio's Gain Cell, which they describe as a "proprietary, fully differential, zero feedback, discrete, class-A MOSFET circuit.In the Stellar M700, the Gain Cell drives a 700ASC class-D power module from the Danish company ICEpower.

  1. I’ve had many amps connected to my power hungry Magnepan 3.6’s. With the new PSA M700’s fed by DirectStream DAC w/Bridge II it’s like I have a new pair of amazing Magnepan speakers. Magnepan is funny. Years ago I got some cheap MMG- W speakers and a cheap center speaker. With my AVR they were ok but nothing more. I got a Oppo 105 and it was suggested that I use the 105 as a pre and hook up a good 4 Ohm amp for the Maggies. I got an old NAD out of storage, bridged it and connected to the center speaker. Suddenley there were real people and music coming out of these cheap speakers. AVR’s don’t have the reserve power for power hungry speakers. The M700’s are the perfect match for big Maggies. You have to hear it to believe it.

    1. Thank you so much for this invaluable info. I had a pair of MG3a speakers for some years. Magnificent. I am very pleased to see that both they and PS Audio are doing so well. Deserved! Regards – Howard
