Product Details

The Stellar GainCell DAC combines the benefits of an exceptional analog preamplifier and a full-featured DAC. It's affordable excellence.

The analog preamplifier is the heart and soul of any high-performance audio system. It’s the point in a system where music’s magic can be won or lost. For more than 45 years, PS Audio has been building preamplifiers that honor the music and preserve the magic. The Stellar Gain Cell DAC is no exception. It features fully balanced class A analog circuitry from input to output, along with a state of the art DAC that ensures perfect symmetry between analog and digital. Rediscover the wealth of music in your library, with Stellar. Rich, sweet, and always a musical treat, Stellar GainCell DAC is our best value in bringing life to music.

 

DESIGN

The idea of building a no-loss analog preamplifier with its own built-in cutting edge DAC was the basis of the Stellar GainCell design imperative. At this instrument's heart is the analog GainCell. Rather than using additional sonically-degrading elements inserted in the signal path to control volume, the GainCell eliminates this problem without additional circuitry in the signal path by varying its gain in response to front panel controls. Based on industry leading Sabre32 bit Hyperstream architecture, Stellar DAC features a fully balanced Class A analog output stage with multiple power supplies, independent jitter-reduced inputs, DSD, I2S, and asynchronous USB.


APPLICATION

The Stellar GainCell DAC is a full function analog preamplifier featuring a state of the art built in Digital to Analog Converter inside. It is all you need as the basis of a reference quality music system. Add a power amplifier and a pair of loudspeakers and you'll be reveling in sonic bliss within moments. Connect a computer, CD player, or digital source to any of Stellar's multiple digital inputs, or a Stellar Phono Preamplifier to its analog ins, and you've just built one of the highest value music systems in the world.
