Ok, I have a Denon 3801 amp and I am wanting to upgrade my whole system to THX Ultra spec. I currently have the KEF homecimena speakers in a 7.1 setup. Now I was thinking of upgrading the amp but feel the upgrade to the speakers first would be better. Would THX spec speakers work well with the Denon 3801 amp? If so has anyone had experience running THX speakers on lower spec amps?
