A quick question for all the axiom/home theatre experts.

I'm looking at the Epic Grand Master 175 system, and I was wondering what if any speakers people would switch in this system, while keeping the price at 1700 CAD. Any comments on the sound difference between Epic Master 175 and Epic Grand Master 175 would also be appreciated.

The wizard gave me m3's, qs4's, vp150 and ep175, compared to m22's, qs8's, vp100 and ep175 in the Epic grand master. price on both was $~1700

System will be used for DVD's, Gaming, TV, and hopefully soon blueray. I don't really listen to music that much.

The room
Basement area is ~14'(east west) x 21' (north south) with 7' ceilings, currently open to the floor joist above. TV will be in a 9'x2'6" alcove in the south edge of the west wall (below the bay window in my living room). Stairs in the middle of the north wall extend 7'6" into the room.

Other equipment
Panasonic TH-50PX80 (720p plasma)
Onkyo TX-SR606

My current 27" tube and DVD player will stay up stairs for the kids.. Taxman is paying for my first real home theatre/home audio system \:\)

Thanks in advance.
