The Relentless Preamplifier is a three-chassis design — the main unit plus two outboard power supplies, one for each channel. This complete separation of left and right power supplies eliminates crosstalk at the source and provides the massive, ultra-clean power rails needed to swing over 40 volts at the output.

The circuit employs a locking fully balanced, complementary, discrete topology throughout. Two-zone, two-source operation allows independent audio feeds to different rooms. The optional Digital Streaming Module adds Roon Ready streaming with Tidal, Qobuz, and Spotify. The Bluetooth Vision remote provides bidirectional control with an aluminum body and display.
