PS Audio Launches PMG Signature S400 and S200 Power Amplifiers for Audiophiles

Explore the new PS Audio PMG Signature series amplifiers delivering 400W and 200W power with top-tier sound quality and sleek design.

A New Era for PS Audio Power Amplifiers

When it comes to high-end stereo setups, power amplifiers are the heart that pumps life into your favorite tunes. PS Audio has recently stepped up the game by unveiling two fresh additions to their PMG Signature series — the S400 and S200. Crafted from scratch by Darren Myers with the engineering finesse of Bob Stadherr, these amps celebrate PS Audio’s 50 years of audio excellence with a bang.

Power and Performance: What Sets Them Apart

At the core of their difference lies raw power. The S400 boldly delivers 400 watts per channel into a 4-ohm load, while its younger sibling, the S200, pumps out a solid 200 watts per channel at the same impedance. Despite these differences, both share an identical chassis design, engineered to partner with a vast range of loudspeakers effortlessly.

Pure Class A Beginnings for Sonic Sweetness

Here's a delightful touch for true audiophiles — both amps handle their initial power output in pure Class A mode. For the S400, that’s the first 5 watts, and for the S200, a generous 10 watts. PS Audio claims this approach enhances sound quality at lower volume levels — you know, those intimate listening sessions where every whisper and breath in the music counts.

Innovative Power Architecture for Crisp Energy Delivery

Moving beyond traditional transformers, these amps embrace an active power architecture. This modern approach ensures a cleaner power supply that can quickly respond to sudden surges in musical dynamics. The result? Amplifiers that serve up energy with precision and clarity, capturing every nuance of your audio tracks.

Cutting-Edge Circuitry and Optimized Design

PS Audio’s engineering magic continues inside with extremely low negative feedback levels and an impressive bandwidth topping 500 kHz. The slew rate zips past 200 V/µs, ensuring rapid and faithful signal reproduction. And with a cleverly optimized chassis, the S400 and S200 minimize crosstalk between left and right channels, preserving stereo purity.

Connectivity options include balanced, single-ended inputs, and bi-wiring speaker terminals

Flexible Connectivity for Home and Theater Integration

Versatility is key for modern audio lovers, and these amps deliver. Both models feature balanced and unbalanced inputs, dual pairs of speaker terminals for bi-wiring, separate subwoofer outputs for each channel, and a 12-volt trigger to seamlessly hook into home theater systems or complex audio setups.
