ARC tube amp recommendation for ProAc 1sc


Hi All,
I've been driving my ProAc 1sc's with a Bryston B60 for many years. It's a nice sounding system, however, I always planned to feed them with tubes someday. Just started doing some research and I see that many recommend ARC as the ideal match for ProAc's. From a power and price perspective, I'm thinking Classic 30, VT50, VT60 or Classic 60.

Does anyone have (or have heard) any of these pairings? Are these all good potential candidates? Or maybe there are other's I should also consider?

Your advice would be greatly appreciated.

You cannot go wrong with the classic 60 though.
Several years ago I heard the ProAcs with an ARC CA-50 (essentially a VT-50 with input stage) and it was wonderful. If you're room is not too large, I can't see anyone not loving this combo. I recently heard what is considered the replacement for the 1sc (I can't remember the model, D series I believe) with the current ARC 60 watt integrated, it too is a great comboto try.
I drive my 1SC's and 140's with the Cayin 100. I did listen to the 140's with the ARC CA-50 a while back but did not feel it had the warmth of the Cayin 100. Note also that I se a VAS Cititation 1 as a pre amp fed directly to the 100 by passing the pre of the 100. Cayin has great sound, and is a great value.
