I purchased a pair of Carbons about four months ago. I agree with the positive comments posted here.
Mine are on the long end of a 15 x 20 untreated room that has an area rug, sectional couch, and drapes. They are three feet from the sidewalls and two feet from the front wall. I sit about ten feet away. Very good sound stage left to right and in depth. One can move around a bit from the "sweet spot" and still get soundstage and focused images.
Also, the speakers will let you hear amp and source changes.
No sharp highs but the detail is there and acceptable bass for me...very enjoyable.
