ARC Pre + which SS amp?

Rwwear, can you be more specific as to which Krell it is, what speakers, etc?

Plinius and ARC seem to go well together.I have run both a Ls 16 and a ref 3 with a Plinius SA 100 mark 3 ( balanced) and have been pretty happy with both.

I've got an ARC SP9 with GNSC Ref mods. I ran it with a Levinson 331 for many years but about a year ago I replaced the Levinson with a McCormack DNA-500. Whoa, what a step up! Amazing dynamics and depth of soundstage. Great match.

My LS25mk2 is very happy paired with Bel Canto ref1000's. IMO a better combination than the LS25mk2 and the VS110.

I'd recommend you try it with your Bryston for a while and see if that works for you. As an alternate, I'd try to give a listen to the ARC solid states. Some of them are quite good - D240, 100.2. You just never know what is going to sound great in your listening room. My 2c. Good luck.
