Apologies, misread "input" as something you can stick a Sooloos Zone (ie MS200) into, rather than output.

I suppose it depends how much M wish to cannibalise their sales of MC200s, as this is currently entry level for Sooloos. It would circumvent entirely the need to buy at least some storage from M, since the only Cores that have no storage are all legacy products (pretty sure the 818 can't act as Core).

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.
