StellarGain Cell Preamplifier

Full featured analog preamplifier and DAC

 

The Stellar Gain Cell™ combines the benefits of an exceptional analog preamplifier and a full-featured DAC. Fully balanced analog circuitry from input to output, the Stellar Gain Cell builds upon years of research and innovation in the art of Class A analog amplification and state-of-the-art digital reproduction. Together, or separately, they create an extraordinarily rich, full-bodied musical experience few standalone products can match. The Stellar Gain Cell is the perfect foundation for those unwilling to compromise sound quality. Rich. Lush. Powerful. A music lover’s answer to spiraling cost-no-object equipment without sacrifice.

The idea of building a no-loss analog preamplifier with its own built-in cutting edge DAC was the basis of the Stellar Gain Cell™ design imperative. Add any analog or digital source to Stellar’s input, a power amp and speakers to its output, and music filled with rich textures and toe-tapping energy surprise and delight even the most critical Audiophile.

At this instrument’s heart is the analog Gain Cell™. Developed in the early 2000’s by PS Audio founder Paul McGowan, the Gain Cell™ elegantly solves the fundamental problem facing preamp designers. Volume control. Nearly all analog preamplifiers use additional sonically-degrading elements inserted in the signal path to control volume. These impediments to the signal path’s purity range from simple potentiometers to exotic stepped attenuators, relays, solid state switches, ladder networks, transformers, light dependent resistors. All share intrusive elements in the signal path. The Gain Cell eliminates this problem without additional circuitry in the signal path by varying its gain in response to front panel controls.

Integrated into this analog preamplifier is a stunning, Bob Stadtherr designed, digital to analog converter. 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.

Together, the Stellar™ Gain Cell preamplifier and DAC make musical magic.
