Overview

Stellar Gain Cell

 

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.

Stellar S300

The problems faced when crafting a new power amplifier are many—delivering sufficient power, control, frequency extension, and dynamics while maintaining a perfectly layered soundstage under the most complex musical passages.

All amplifiers sound different. What determines sound quality are the components and topologies of the amp’s input voltage stage and output current stage. Each section should complement the other. Between them, the amp develops its sound.

Stellar’s design imperatives—affordable pricing, and uncompromised sonics—were major challenges solved by the invention of a unique new circuit christened the Analog Cell™.

Stellar engineer Darren Myers had planned from the outset to take advantage of Class D’s high current, low distortion, ruler flat linearity for the output stage—knowing full well it is the input stage that determines sonic character. This critical interface between preamplifier and power amplifier is where Stellar’s magic would be unveiled; where Myers could lavish upon the music the sweet, tube-like quality of Class A biased MOSFETs. His challenge was to synergistically marry both input and output topologies, for which he invented Stellar’s Analog Cell.

The Analog Cell is the heart of the S300’s musicality, where richly overlayed layers of music’s inner details are preserved even in the most complex orchestral crescendos. The Analog Cell is a proprietary, fully differential, zero feedback, discrete, Class A MOSFET circuit, hand-tuned to capture the smallest micro dynamics without sacrificing the loudest macro dynamics music has to offer.

If you’re able to invest in a cost-no-object performance stereo amplifier, you want the BHK Signature 250. For everyone else who refuses to compromise music’s promise, Stellar represents breakthrough performance at stellar pricing.
