Thanks. I've been taking the advice of others and listening. As you know I have a Aperion 5C Center and I'm looking for a "cleaner" and bigger sound stage. This is the primary reason for upgrading.
I currently have front ported towers (6T) and was looking for a cleaner sound in that area also. They are a bit boom and its because of my room. Audyssey really tames the 6T's below 80hz.
So - I prefer technically accurate/neutral and maybe slightly forward sound that can be played at 93dB (with 103db spikes) without ripping my ears out with harshness. So if you recommend a few good options and I'll try my best to listen to them.
To help with my room issues, I'll be putting Corning 703 as basic room treatment, although that wont help with bass much i think..
Currently, I'm torn between going with a sub (and knowing I cant really get down to 16-25hz) or towers.
