There's a lot I question about my current setup!

I didn't know much about HT back then (obviously, or I wouldn't have gotten a wall unit that limits me to a 27" TV! Replacing the wall unit really hurts the HT budget, but we'll see).

Actually, the reason for my original post was that based on all I've read i'm not sure either position will do the M22s justice because they'll be too high and/or too far apart. I don't want to spend that much and then compromise their performance. Would anyone have suggestion of othe systems with similar price/quality that might work better with the room?

Thank you all for your advice.
