Fishwater,
Funny you should say that- planning to sell BAT in favor of some SS amp.
I have the same speakers and just recently sold Theta Digital Dreadnaught II, thinking of BAT as one of the options to replace it.
Could you please share, what is it exactly that you DON'T like in BAT sound?
BTW, I'm listening to Butler 5150 now, and like it a lot.
Regards.
