Preaching to the choir. In my case anyway. For anyone who thinks they have as good a system as can be regardless of cost in an untreated room, pay attention to what hilde45 posted. I only listened to 2/3 of it because I already experienced all of it. A properly built and treated room will get you to a higher level of audio nirvana that you ever thought possible. Equipment alone will only get you a fraction of that.
"The room can totally wreck, or make, a system"
For those interested in dealing with the most important part of their system -- indeed, the precondition for a good system: the room.
