I'm new here and was previously running a pair of Polk t600s (monitor 60s in canada) off of my Denon AVR-891. It sounded fine, but I've decided to upgrade my system and was curious if this should still provide enough juice or if I should look into upgrading my Amp. I've purchased 2 RTi A7s, a CSi A4, and 2 RTi A1s to run in a 5.1 set up. I'll look at adding a sub in a couple months. Will my current amp be able to handle these speakers adequately?
