PS Audio of Boulder, Colorado, USA have launched their new Stellar S300 Stereo Amplifier, M700 Monoblock Power Amplifiers and Stellar Gain Cell DAC.

S300 Stereo Amplifier

PS Audio say: “Breathe new life into your loudspeakers with the Stellar S300, one of the most extraordinary under $5,000 stereo power amplifiers ever crafted. The S300 combines the slam, linearity, and toe-tapping pacing of a Class D output stage with the warmth, grace, and rich inner detail of Stellar’s Class A Analogue Cell. The results are nothing short of ground breaking“.

Stellar Gain Cell DAC (DAC and analogue preamplifier)

PS Audio say: “There isn’t a DAC made that doesn’t benefit from a great analogue preamplifier. The Stellar Gain Cell DAC combines the benefits of both—a full-featured DAC with an exceptional analogue preamplifier controlling its output level. Fully balanced circuitry from input to output, the Stellar Gain Cell DAC builds upon years of research and innovation in the art of digital audio and Class A analogue amplification”.
