Product Description

PS Audio Stellar S300 Stereo Power Amplifier takes a hybrid approach merging zero feedback MOSFET input stage and class D output stage with each channel having its own power supply. The Stellar S300 gives your loudspeakers a complete boost, elevating the bass and revealing the finest micro details in your music.

Breathe New Life Into Your Loudspeakers

PS Audio Stellar S300 drives 140 Watts per channel into 8 ohms and 300 Watts per channel into 4 ohms. It is evident that the Stellar S300 delivers sufficient power and control, and faced with the issue of maintaining stunning musicality and a deep soundstage, it succeeds exceptionally. This power amplifier is capable of providing the deepest, three-dimensional soundstage whilst recovering the most subtle details and rich layers in even the most complex musical passages.

Hybrid Design

The Stellar S300 benefits from the fusion of ultra linear, high-current, Class D output and a discrete, zero feedback, Class A MOSFET input stage called the Analog Cell. The Analog Cell's sonic character is designed to engage you with richness and warmth whilst the the Class D output stage gives the S300 its great power handling and authority over the loudspeaker.

Engineered by Darren Myers

The Stellar was engineered by Darren Myers who understood the importance of the Class D's low disortion, high current, flat linearity character on its sonic abilities. The critical interface between power amp and pre amp is where Myers employed the Class A based MOSFETS to cultivate its sweetness and warmth on the music. Coupling input and output stages in this way brought about the invention of the Analog Cell.

Analog Cell

The Analog Cell is the beating heart of the Stellar S300’s musicality, where the richest layers and finest details are preserved in even the most complex musical sequences. This is the critical connection between preamp and power amp. The fully differential Analog cell is a zero feedback, balanced, Class A MOSFET input stage, designed to capture the finest musical nuances without compromising the loudest macro dynamics from your speakers.

Uncomporomised Sonics

Stellar represents extraordinary performance at great value. It provides you with the power and grace to compliment your speakers perfectly and ensure your music sessions are heard with pure emotion, warmth and detail. Uncompromised sonics and state of the art topologies promise a groundbreaking performance from the Stellar, every time.
