I'm finally moving, so I will have my (effectively) Epic Grand Master system in a proper HT setup w/ Hitachi 51" t.v. (I saw effectively because my current cneter is a vp-50 instead of a -100).
Now, my receiver is a H/K AVR-120, 45 watts per channel. I find it pretty powerful for that convervative rating. However, there are some pretty good deals out there from Denon for example where I can get 75+ watts, and have component switching for example. As well, my QS-8s are 6-ohm and my receiver is rated 8, thought I haven't had any issues thus far.
I'm currently running the whole setup in my bedroom until i take possession of my apartment, so I haven't really had an open room to test them in.
Will I really notice a difference?
