Introduction

The Stellar M700 is PS Audio’s formidable monoblock amplifier, combining raw power with refined musicality. Each unit delivers 350 watts into 8 Ω and 700 watts into 4 Ω, with effortless stability down to 2 Ω. Designed for serious system builders, the M700 brings astonishing dynamics, deep bass, and lifelike nuance to any loudspeaker.

Design

At its core, the M700 blends two complementary technologies: a discrete, Class A MOSFET “AnalogCell” input stage preserves micro-detail and tonal richness, while a high-current, ultra-linear Class D ICEpower module provides the muscle for commanding drive and high efficiency. The result is a dual-mono monoblock that couples precision and power with minimal footprint and heat.

Application

Ideal for both two-channel and multi-channel systems, a pair of M700 monoblocks can be placed directly on each speaker or run into a preamp for more traditional setups. Whether driving compact bookshelf monitors or full-size floor-standers, the M700 maintains composure up to ear-splitting levels, rendering every dynamic shift and harmonic texture with authority.

Technology Overview

• AnalogCell Input Stage
  A zero-feedback, fully differential Class A MOSFET circuit that sets the sonic character by capturing delicate overtones and spatial cues.
• ICEpower Class D Output
  A Danish-made 700ASC power module delivers high-current output with low distortion and an impressively low idle draw.
• Galvanic Isolation & Trigger
  Balanced XLR and single-ended RCA inputs are fully isolated, and a 3.5 mm DC-trigger port enables synchronized system power control.
• Efficient Power Management
  Low idle consumption (23 W) and high overall efficiency allow for compact, passively cooled operation without sacrificing performance.
