CD / SACD players and transports — Rega VALVE ISIS

Description, images, technical data and specifications

The VALVE ISIS is a distinctive tube-informed CD player from Rega, sharing the ISIS's chassis dimensions with a valve-informed output stage. The VALVE ISIS brings Rega's considered engineering to disc-based digital source playback with a warm tube-informed character.

Key specs that matter

Frequency response for CD spans 30Hz to 20,000Hz within plus-or-minus 3dB. Output impedance is 600 ohms on both balanced and single-ended connections - somewhat higher than the standard ISIS's 560 ohms. Total harmonic distortion plus noise is 0.0013%, matching the standard ISIS. At 434 x 112 x 350mm and 19.5kg, the VALVE ISIS shares the standard ISIS's chassis dimensions with a modest increase in mass reflecting the valve output stage.

Sound and use context

Expect the warm, richly textured character valve-informed output stages are broadly celebrated for, combined with Rega's broader accomplished CD-transport engineering philosophy.

Pairing

Rega's own amplifier catalogue offers natural, brand-coherent pairings within the same broader catalogue.

Alternatives

Rega's own standard ISIS offers a purely solid-state alternative within the same broader digital source catalogue.
