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.
