Hi Dave,
Again what a great system. I have always wanted to hear the Apogee speakers. I was out of high end audio during their reign as top dog. My friends still rave about them. It is to bad that Magnepan put them out of business and then has never used their technology to build a new speaker. It seems obvious to me that Magnepan should be building an all ribbon system . . . I owned MG IIIs for years and never had a problem, I bought a pair of 3.6rs and had nothing but problems. No matter what I did, the ribbon tweeter would blow, Magnepan couldn't even solve the problem.
Does your cat like to listen too? Mine does.
If you haven't started appylying dry wall yet, look into building a room with resilient channel. I based my system on ASC's (ASC.com) Iso-Wall and the sound is incredible.
It seems that it would be icing on the cake with the construction you've done so far.
Do you really think your floor makes that much difference?
I hadn't heard about doing this when I built my room, but I guess I could remove the components and carpet and put down the a floor simalar to yours. Live and learn.
