The fully balanced 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 Gain Cell input stage.

Rated at 340 Watts into 8Ω and 700 Watts into 4Ω while stable into 2 ohms. 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 gain Cell for the
all-important input stage. The M700’s rich, warm, and engaging sonic
character comes from the Analog Gain Cell. Its powerful,
authoritative control over the loudspeaker stems from its high current,
ultra-low impedance Class D output stage.

Stellar’s design imperative was to produce a truly musical
sounding power amplifier that proudly competed with any amplifier under
$5,000. PS took the
challenge and set to work on a new concept—a hybrid that would combine
the best of today’s technology with time-honored techniques leveraging
PS Audio’s forty plus years of experience.

The results are extraordinarily musical.

The Analog Gain Cell is a zero feedback, balanced, Class A, MOSFET input
stage. The design closely mirrors the sonic characteristics of a vacuum
tube and allowed PS the freedom to voice the amplifier as they see fit.

Available in black or silver. We also have the 140wpc stereo S300 available in both colors. It does 300 watts into 4 ohms.
