I find it hard to believe that yours 60's aren't LOUD enough. My Denon 2805 and 60's combination is plenty loud, unless you want to go deaf. Don't get me wrong, I like cranking it up from time to time, and have been to many concerts with insane dB levels. I find it hard to believe your 60's don't make you happy.
I would try checking SPL, and possibly a different receiver before opinions of the 60's are made
60's 150 350 4-Qs8's
