I wanted to jump in on the first post.
I have a question to the OP and an observation to share.
Have you ever recorded your system and then listened to the playback?
When you walk into a room wether you are conscious of it or not you sense and size up the room almost immediately. You could walk blindfolded into most any normal space and know if you were indoors or not, in a small room or large, in an absorptive or reflective space and likely roughly guess the ceiling height in a few seconds and your brain does the processing to allow you to hear the source of interest straight through most of the environmental effects. When you listen to something recorded in another space and the recording includes the sonic signature of the environment you have little ability to process or filter out the effects of the environment. It's similar to attempting to solve something encrypted without the key.
Try it, record your main system and go listen to it on your computer. Even though you are familiar with the space, I think you will be surprised at how unfamiliar it sounds. Be warned, it will likely make you unhappy.
