I guess I really am old cause I almost pooped my pants after reading that. Or maybe I should say I almost Bosed my pants.
That would be redundant and a waste of a Sherbourn IMO. In a blind test you likely won't hear a difference. Of course your ears may be better than mine. That's my escape clause for the guys who have golden ears. Personally I would sell the Sherbourn or use it in a 2nd system where you don't need the receiver's bells and whistles.
