DESIGN

The Stellar S300 stereo power amplifier is a dual mono power amplifier capable of effortlessly driving demanding loudspeaker loads to concert levels. It combines the best of two worlds: ultra linear, high-current, Class D technology for the output stage; a discrete, Class A MOSFET based Analog Cell for the all-important input stage. The S300's rich, warm, and engaging sonic character comes from the Analog Cell. It's powerful, authoritative control over the loudspeaker stems from its high current, ultra-low impedance Class D output stage.

APPLICATION

The perfect choice for just about any loudspeaker, the S300 slips into any system, surprising and delighting even the most discriminating Audiophile. Rated at 140 watts per channel into 8‎Ω and 300 watts per channel into 4‎Ω, the S300 has plenty of horsepower for even the most demanding loudspeakers. Your musical library will open up in ways you might not have thought possible, revealing nuance and detail covered up by traditional amplifiers.

The S300 is an extraordinarily musical power amplifier rated at 140 Watts per channel into 8Ω and 300 Watts per channel into 4Ω. Power enough for even the most demanding speakers. The S300 design marries the best of two worlds: an ultra linear high-current output power stage with a discrete Class A MOSFET based AnalogCell input stage. Between them, the S300 delivers powerful, authoritative control over the loudspeakers, while maintaining a perfectly layered soundstage under the most complex musical passages. Designed by PS Audio engineer Darren Myers, who invested hundreds of hours of tuning, voicing, and perfectionist tweaking, the results are extraordinarily musical. Stellar amplifiers never draw attention to themselves, and are one of our highest value offerings in amplification, a rare quality in amplifiers of any price.
