Extreme Power, Dual-Mono Construction, Authoritative Control, Mammoth Headroom: PS Audio Stellar M700 Monoblock Power Amplifiers Offer 700Wpc Output, Drive the Most Demanding Speakers

If you've always dreamed about anchoring your system with a pair of authoritative monoblock amplifiers that effortlessly drive practically any speaker on the planet but never believed you could afford them, the PS Audio Stellar M700 amps are made for you. Hand-built, made-in-the-U.S.A., full-size, and dual-mono in construction, Stellar M700 sound tremendously natural, detailed, musical, and open. They provide mind-boggling grip, depth, and control courtesy of 340Wpc into eight ohms and a whopping 700Wpc into four ohms. Combining slam, linearity, and pacing with grace, richness, and warmth, Stellar M700 constitute a new kind of hybrid steeped in traditional and modern technologies. Designed by Darren Myers, they utilize ultra-linear, high-current Class D operation for the output stage and a discrete, Class A MOSFET-based Analog Cell for the crucial input stage. Stellar M700 deliver bold results that components at their price point have no right to offer. You'll love their spacious, effortless, dynamic presentation, mammoth headroom, non-aggressive character, subterranean bottom end, fantastic soundstaging, and extreme energy. 100% Music Direct Guaranteed.

The secret to Stellar M700's price-to-performance-busting abilities resides with their Analog Cell topology that provides a zero-loss interface between the preamp and DAC. A zero-feedback, balanced, Class A, MOSFET input stage, it closely mirrors the sonic properties of a vacuum tube and conveys music with utmost faithfulness. Carefully voiced by Meyers, M700 preserve the key details, subtle cues, soundstage dimensions, and instrumental overtones many amplifiers fail to retain. These are the very traits necessary for engaging, emotional connections to your favorite records. Just as important, M700 tout marvelous pacing, glare-free playback, and control over even very complex passages. Let's not forget M700 are built by hand in Colorado. No cheap Chinese manufacturing or third-party parts here. PS Audio has thrown down the gauntlet with M700 – a pair of monoblocks entirely deserving of their Stellar badge.

“I have had nothing but good experiences with PS Audio products; still, with the Stellar M700, my expectations were exceeded. Having little sound of its own, the M700 delivered well-balanced reproduction that was always faithful to the music.”
—Robert Deutsch, Stereophile, February 2018

Analog Cell Topology Preserves Details, Nuances, and Richness
The connection between preamplifier and power amplifier is the junction where most essential musical details are easily lost. When it comes to preserving music's finest nuances, nothing in a power amplifier is more important than its input stages. In M700, Analog Cell topology is employed to preserve music's rich details. Long hours of listening and tuning sessions in Music Room One, shared by PS Audio founder Paul McGowan and designer Darren Myers, resulted in a sonic signature that honors the music and never draws attention to itself.

Dual-Mono Design with Separate Independent Power Supplies
Stellar M700 employ a dual mono design, meaning each channel in each amp has its own, separate power supply. Each of the two channels is a complete and independent power supply and power amplification stage, based on a modern Class D ICE module. Class D output stages' strengths are many: Near-perfect linearity, low distortion, high efficiency. Stellar M700 provide excellent frequency extremes, low distortion, high damping factor, and a staggeringly powerful output of 700Wpc into the most common loudspeaker loads of four ohms.
