700 Watt Analogue Cell MonoBlock Power Amplifiers


The PS Audio Stellar M700 Monoblock Power Amplifier 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.

What is Analogue Cell?

Analog Cell is a zero feedback, balanced, Class A, MOSFET input stage. The design closely mirrors the sonic characteristics of a vacuum tube. The Analog cell produces the richly overlayed layers of music's inner details. It captures the smallest micro dynamics without sacrificing the loudest macro dynamics music has to offer.

Output Stage

The hybrid approach used in Stellar's power amplifiers takes advantage of the best traits technology has to offer. Its all-important input stage relies upon the Analog Cell to provide a zero-loss interface between the preamplifier or DAC, as well as imprint the amp's sonic character. It is then time to convert the perfected analog voltage into the all-important high current output needed to drive loudspeakers.
