Here is a link to their website. I have recently auditioned the 200 and 600 series. Sorry, but I did not get to hear the 100s. As for what I did listen to, I was and am thoroughly impressed. The speakers seemed to disappear from the room, while the sonic placement of vocals and instruments was contained in a high, wide soundstage that seemed to magically "appear" in the listening area. I just ordered a 5.2 HT set-up based on the 208.2s. It should be up and running in about 2 weeks or so. I can then give you, if desired, more detailed information based upon my (planned) extensive listening sessions.
