Forgot to mention the processor needs room correction as well.
"and what to do for the amp or amps... i love how the anthem makes my speakers sound"
With that statement(pardon the pun), you expressed how very pleased you are with the Anthem P5. I don't know what you paid for the P5 but you indicated in one of your previous threads that you got a very good deal on it. It is a musical powerhouse. I bet it would be hard to replace such a quality amp for what you paid for it.
Not sure what kind of bliss you are trying to achieve, but your current setup and gear should be giving you just about everything one asks for in a "home theater". The only minor thing I see is the in the bass dept.. As mentioned before in a room that size it would be best to add a nice sub (JL Audio F112, B&W ASW 825, REL Stadium or SVS PB Ultra 13 & Epik subs )and maybe use your current sub in an alternate area in the room (maybe the absolute rear). This should give you the in your chest feeling during most scenes if you are not experiencing it yet. HSU subs are good too, my buddy has one and I love the deepness his produces, but his setup is purely musical and not HT.
Thank you for the responses. i am just throwing around some ideas. maybe just a good processor and newer sub is all i would need. after the purchase of the new center channel, i am close to being taped out cash wise. so the thought was sell the amp and receiver, use the money to buy a good amp and processor with ghetto proceeds, but i do jot want to go backwards in quality. emotiva released their new 5 channel amp ($2000) and there is not a review out there yet. i did jot know how that would stack up against the anthem.
but... for now maybe just the elite can get sold and get a processor, even though the elite decodes and has everything but the xlr connections that i want, the sound from a dedicated processor, i am told, would be better.
