Rega ISIS Valve

General Information

The valve Isis shares the same digital and USB sections as found in the solid state version however the analogue stage is valve based with passive filtering. This stage uses two military specification triple mica 5814A (ECC82/12AU7) triodes being driven by the revolutionary Wolfson WM8741 ultra high performance digital to analogue converter.

The output buffer and transformer driver stage uses two ECC88 (6DJ8/6922) triodes. This, like its solid-state stable mate, is of an un-orthodox design. The design goal with this player was to keep away from the normal design approach of "lets run it through a valve to make it sound warm", but take advantage of industrial valve circuits to make an articulate and competent valve based CD player. Careful choice has been made for every component in the digital and the analogue signal path to ensure the integrity of the signal.
