This is the hobby that can break the bank, but I love it. I have upgraded none stop for about a year now. I going slow down for a while and try to match the best cable for my system. Once I and done with that I will be adding the Conrad-Johnson MF2500 amp and another pair of M20's to go to 7.1.
Update: I am also getting to sell the Servo15 and go with the Revel B-15 sub.
Update 8/29/03:
I have done some chances to my system since the last update. I did add another pair of Revel M20's for my 7.1 and i must say it added to my home theater more than I thought it would. I have a large room and this really helps fill in my surounds. I also changed my speaker wire for the front three to the BetterCables Blue truth. I is a wonderful sounding cable. It bought out details without sounding bright. Another big change is I bought the new Rotel RSP-1098 with the TFT screen. It's new so I am waiting for it settle down alittle, but it has some really nice feathers. I do a better review after it breaks in.
Your system sounds great. I own the M20s, too. (I'm a two channeller, though) Anyway, if you want to go where you've never been and not change a thing: just add an Audio Magic Stealth. Plug in your stuff and you'll go to places you never thought possible. An addition you won't regret.
