PS Audio Stellar M700 Monoblock Power Amplifier (Pair)

  • 700 watt Analog Cell power amplifier pair

Enjoy an unheard of level of control and command from your loudspeakers with the Stellar M700, one of the most extraordinary under $5,000 power amplifier pair ever crafted. The M700 combines the slam, linearity, control and pacing of a Class D output stage with the warmth, grace, and rich inner detail of Stellar’s Class A Analog Cell. The results are nothing short of breathtaking. Liberate all the toe-tapping energy trapped in your media library. Plumb music’s subterranean depths as your system gives you more bottom end than you thought possible. Revel in rich layers of fine, full detail. Marvel at the deep, extraordinary, wall-to-wall soundstage. Control your loudspeakers as never before. Effortless. Lush. Stellar.

The problems faced when crafting a new power amplifier are many—delivering sufficient power, control, frequency extension, and dynamics while maintaining a perfectly layered soundstage under the most complex musical passages.

All amplifiers sound different. What determines sound quality are the components and topologies of the amp’s input voltage stage and output current stage. Each section should complement the other. Between them, the amp develops its sound.

Stellar’s design imperatives—affordable pricing, uncompromised sonics—were major challenges solved by the invention of a unique new circuit christened the Analog Cell. 

Stellar engineer Darren Myers had planned from the outset to take advantage of Class D’s high current, low distortion, ruler flat linearity for the output stage—knowing full well it is the input stage that determines sonic character. This critical interface between preamplifier and power amplifier is where Stellar’s magic would be unveiled; where Myers could lavish upon the music the sweet, tube-like quality of Class A biased MOSFETs. His challenge was to synergistically marry both input and output topologies, for which he invented Stellar’s Analog Cell.

The Analog Cell is the heart of the M700’s musicality, where richly overlayed layers of music’s inner details are preserved even in the most complex orchestral crescendos. The Analog Cell is a proprietary, fully differential, zero feedback, discrete, Class A MOSFET circuit, hand-tuned to capture the smallest micro dynamics without sacrificing the loudest macro dynamics music has to offer.

Really good power mono block amps that look the part as well.
Very smooth yet detailed and lots of power on tap.

These mono-blocks have musical weight, timbre, transparency, and sound stage on a par with some top notch mono-blocks. Yet, they use less energy, and produce less heat. The build quality is robust. However, they are not heavy like my previous mono-blocks, so you can clean your racks once in a while without scratching the racks, damaging amp’s feet, them or cutting your own hands 😊
