Rega Valve IsisValve CD Player

The Rega Valve Isis is a premium valve-based CD player that combines advanced digital technology with classic valve amplification to deliver warm, articulate sound and exceptional signal integrity. Designed by Rega's head electronics engineer Terry Bateman, it offers superior audio performance for discerning audiophiles.

After 10 years of research, the Valve Isis integrates valve amplification in the CD player's output stage, inspired by musical instrument and recording amplification techniques since the 1950s. Its straightforward circuit design leverages the technical and sonic advantages of valves within a differential instrumentation amplifier, driven by a differential output DAC and a passive LC filter.
