I can confirm the iTache works with DSP33s.

The MS200 ought to work with a Reviver, although one set of DSP33s this was the case but I couldn't get the setting right in the second set. Switching inputs is done with an MSR provided the speakers are properly set up.

Sooloos, Roon, G series (with LPS upgrade), 800 series (with LPS upgrade), HD621, AC200, Prime and PS, DSPs old and new.

Purdeys, Moke, Leica, 'Blad. Only the best.
