About the S300
The PS Audio Stellar S300 is a high-performance stereo power amplifier designed as a dual-mono Class D unit with separate power supplies and amp stages for each channel. It utilizes a proprietary fully differential zero-feedback discrete Class A MOSFET Analog Cell input stage paired with a modern high-current ICEpower 300ASC output module from Denmark. This hybrid design delivers excellent linearity, low distortion, high efficiency, and superior bass control via a high damping factor. The amplifier excels in driving demanding loudspeakers, offering precise soundstaging, clarity, dynamic power, and extended frequency response up to 50kHz. It supports both unbalanced RCA and balanced XLR inputs, with copper base nickel-plated binding posts for speakers. Available in black or silver finishes, it is factory-set for specific regional voltages and includes a 3-year warranty. Reviews praise its musicality, value, and performance comparable to more expensive amplifiers.
