PS Audio StellarGold Preamplifier

Design

The StellarGold Preamplifier features two hand crafted discrete audio amplification stages, both enjoying extremely high slew rate, high bandwidth, low distortion signal handling capabilities that honor the music. Based on a combination of JFET and BJT devices along with hand-selected purist components, the musical signal is delivered without the interference of capacitors in the signal path. Each amplification stage is based on a minimal global feedback design that achieves its low distortion status through careful balancing and high current design choices. Lastly, its high current class A output stage is more than capable of driving long cable lengths without compromise so that your power amplifier enjoy all the benefits StellarGold Preamplifier has to offer.

Application

Preamplifiers are the heart of any standalone audio system, controlling musical sources like DACs, phono preamps, and tuners. Bridging these sources to your power amplifier without adding any kind of sonic thumbprint is a challenge the StellarGold preamplifier takes on without any hesitation. Life, energy, and a sweet analog presentation are at the heart of this remarkable piece of equipment’s performance. The StellarGold Preamplifier features 4 identical balanced and single ended inputs, and converts all input signals into a balanced signal for the lowest possible distortion, and can be used in a two-channel audio system or as part of a home theater system.
