Thanks for the feedback guys.
About 90% of my listening is not a problem, very moderate levels. The problem is that it's the 10%, at levels of about 90db +/- peaks (Radio Shack sound meter) that I live for!
I use Belles and Forte II's, in two separate setups. My listening, at volume, is rock. Definitely not condo friendly! I guess I was hoping for a "magical" solution, as I know that condo living isn't conducive to any energetic music listening.
Unfortunately I'm probably looking at a one level flat, which likely would have a common floor/ceiling above, and would have a floor over the parking garage. It's a 3-4 year old, stick framed building. It should have pretty good acoustic isolation for day to day living, but not for my purposes! Still, any suggestions that might allow for some raised level listening, while still allowing me to be a good neighbor, would be greatly appreciated.
