Nucleus Gallo Solo or Reference. These are the older version that's been discontinued, not the newer HT focused speaker line. These don't come up used all that often, but there is a pair on Agon right now. Check out the reviews on AudioReview. These speakers are the most transparent, best imaging, 3d, blah, blah, blah speakers I've ever heard and I've heard all the big boys. They are not the ultimate in low frequency extension and I don't think they mate all that well with a sub, but from 80hz on up they are simply stunning.
