In this room, there are two systems. A 2-Channel stereo system, and a separate Home Theater system for movies. These two systems only share the subwoofers. The 2-Channel system has been my hobby for the last 27 years. It has gone through many reincarnations, and still a work-in-progress, but I can't believe the level of sound quality that it has reached. My frame of reference has always been a Jazz ensemble playing on a stage right in front of me, or a live performance in a closed space. When I raise the volume loud enough and set the lights real dim or close my eyes, I can imagine the performance in my room. It's an amazing feeling. Each component in the system has added something special to that image over time.
