I own a Vitus SIA-025 Mkll, and the Ultra Fine detail is excellent. Yes, when in class A mode.I had a good listen to this at Munich and is fantastic - was one of my companion's favourite rooms.
Usual Vitus attributes of lovely class-A creaminess, rich tonality, stunning vocals. It's a great partner to the Rockports too. If I were to criticise, it's also the usual Vitus attribute of smoothing over some of the ultra-fine detail.
Obviously no idea how it would compare to SIA-025 without back-to-back.
I’m sure the SIA-030 ultra Fine detail is great too, and probably better than SIA-025 Mkll. Why, because SIA-030 preamp section is better, amongst other things.
Does anyone know the USA retail price yet? I like to order one soon, but I need price first. I’m not preordering without price. Siltech
