I am happy with my setup, but you know ...... I think the term is "upgaditis", as heard and diagnosed on this forum.

Anyways to my question, 5.2 OR 7.1? Which would add the most punch to a home theatre? (by punch i mean noticible improvement not bass)

The two scenarios...

a) add a sub to my existing system possibly another 175 or 350.

********I was also wondering if matching my 175 with say a higher end sub (like the ep 500, 600, big SVS or Hsu) would totally knock the 175 out of the room? Or with they work well together?********


b) Add a couple more Qs-8s to the sides of my seating arrangment.

*****Or even move my qs-8s and put a couple of m22i's as rear surrounds. I know that a few of you have used the m22i's as rear surrounds. Have you heard Qs-8s and what made you go with front-firing rears?******

There are actually 4 scenarios here. This is obviously for finding peoples opinions, so any ARE appreciated!

TIA
