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.
