Phono RPS 100

About the Phono RPS 100

The TW Acustic Phono RPS 100, also known as the Raven Phono RPS 100, is a high-end, tube-based phono preamplifier with a separate power-supply chassis. It uses two-stage amplification, active equalization, MC input transformers, matched 12AX7 and 6922 tubes, selectable cartridge loading, five equalization curves, independently configurable inputs, phase inversion, and front-panel memory-controlled operation. The manufacturer’s current product page lists the RPS 100, so it should not be classified as no longer manufactured. Published specifications do not provide complete measurements for frequency response, THD, signal-to-noise ratio, output impedance, or maximum output level.
