That is nice.  I was hoping one day i'd upgrade to a old Adcom 3 channel amp, but until then i will live vicariously through others.  Congrats on your new purchase, i'm sure those 5B's will sing with that XPA-3 and 12D you've got going on in there.    I couldn't imagine you'd ever want anything more in that room

 Oh, you might not need those fans on the Onkyo anymore seeing as how you've dropped the load of the front 3 channels?
