There isn’t a DAC made that doesn’t benefit from a great analog preamplifier. The Stellar Gain Cell DAC combines the benefits of both—a full-featured DAC with an exceptional analog 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 analog amplification. Together, or separately, they create an extraordinarily rich, full-bodied musical experience few standalone products can match. Stellar Gain Cell DAC 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.

More details 
Even the best DACs in the world benefit from a zero-loss analog preamp. That fact was the basis of the Stellar Gain Cell design imperative. Combine a cutting edge DAC’s output with a no compromise analog preamplifier. A unique combination of a gorgeous full-featured digital to analog converter and state of the art analog amplification. 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 the heart of Stellar Gain Cell DAC 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.

The DAC’s output level is controlled by 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.
