I purchased these speakers a few months back. They are lovely. Excellent imaging with the lateral imaging being much better than average. They also have sort of a dual personality. The mid-range is beautiful and extremely transparent and works well with tubes at low levels. However, they are also dynamic and capable of producing bass down to 20hz at high db provided you have a high-powered amp. The most exceptional qualities are the pitch accuracy and stellar bass. While the mid-range is great, that is not so hard to find with the quality of today's speakers. The negatives of the speaker are that while they excel at low levels and at high levels, the in-between volumes are not as exceptional as the two extremes. I have not had the time to really break them in. I doubt they have 50 hours on them so things should improve. They seem like a perfect speaker for someone who does home theater but also enjoys moderate levels with tube gear, like myself.
