Product Description
PS Audio Stellar S300 Stereo Power Amplifier uses a hybrid design that merges the input and output stages with each channel having its own power supply. The Stellar S300 gives your loudspeakers a complete boost, elevating the bass and revealing the finest nuances details in your music.
Breathe New Life Into Your Loudspeakers
PS Audio’s Stellar S300 drives 140 Watts per channel into 8 ohms and 300 Watts per channel into 4 ohms. With sufficient power and control, it delivers stunning musicality and a three-dimensional soundstage, whilst recovering the most subtle details in even the most complex musical passages.
Hybrid Design
The Stellar S300, engineered my Darren Myers, benefits from the fusion of an ultra linear, high-current, Class D output and a discrete, zero feedback, Class A MOSFET input stage called the Analog Cell, which is the beating heart of the Stellar S300’s musicality. The Analog Cell's sonic character is designed to deliver richness and warmth whilst the output stage provides great power handling and authority over the loudspeaker.
Uncompromised Sonics
The Stellar S300 power amp 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 aim to deliver a groundbreaking performance.
