Our High Gloss M-80's are hooked into our basement theater, but are being run as a two channel system for now.

So far, I have listened to David Sanborn, Roger Waters, and Fourplay.

My initial thoughts are these speakers are quite a find. (Ok, so a lot of you found them first ... ).

The Soundstage they throw is amazing. The Roger Waters SACD "In the Flesh" is an absolute wonder for discovering a system's soundstage. During the part where "Hal" is talking to "Dave", as in the movie "2001", "Hal" sounded like he was off to my right, in the middle of the room. For a second, I thought I still had a 5 channel system hooked up, but there are only 2 speakers in the system.

For a first day of listening, I am impressed.
