I wrote the comments below years ago. I will keep them for a while as a reminder of my newbie thinking at the time. This hobby is a series of plateaus. I have reached a new one with my current gear. Having a lot of fun.

Have made quite a few changes to this system as my fledgling knowlege of audio has begun to mature. I still have a long way to go...in the knowlege department! I probably won't change components for a while. My goal is best possible 2 channel playback with secondary theater application. Have dedicated room 24 x 17 x 11. There are 5 dedicated 20 amp circuits. My recent focus has been on minimizing negative effects from the room. I have recently added ASC tube traps behind the main speakers and in the ceiling behind the listening position. The most interesting thing I did was to cut a 50x12" hole in the double sheetrocked wall behind the main speakers. There is a large floor to ceiling enclosed cavity that I filled with fiberglass. Then we covered the opening with an ASC custom built sound plank with an open back. The other issue I have worked on feverishly is speaker placement. Getting that right really improved clarity. timbre, and air. Before there was a bit of "congestion" in the sound. Finally, the bass trapping did more for the quality of the bass than I would have expected. Now I have zero bass boom; very tuneful low frequency. Nothing is perfect, but I (with the help of many others!!), have really achieved an outstanding quality of 2 channel music reproduction. Maybe now it's time to focus on the theatre side for a while.
