PS Audio
S300 Amplifier
The PS Audio Stellar S300 is a stereo power amplifier rated at 140 W per channel into 8Ω and 300 W per channel into 4Ω, with stability for musical transients at 2Ω. Its topology combines an ultra-linear, high-current MOSFET output stage with a discrete Class A MOSFET-based AnalogCell input stage and dual mono operation with separate power supplies. Connectivity includes RCA single-ended and XLR true-balanced inputs, along with dual copper, nickel-plated binding-post outputs per channel.
