would you upgrade from VP100 to VP150 or QS4's to QS8's? just trying to get an idea what's the bigger performance gap. I know with my current (polk RM series II) HT setup I always seem to have issues hearing dialog clearly. I sit about 12' from the tv. this tempts me to go to a VP150, although maybe the VP100 is even that much better than my polk?

I have a bigger space (loft condo) but can't get full use out of a "killer" system due to neighbors. so, I'm trying to build great sounding HT setup that I get full use of (no sense getting a huge sub, etc). I'm sure anything I get will be a great improvement over my polks anyways. does this system seem decent?

then either..

QS4's/VP150 OR QS8's/VP100
