Yes, I own a pair, I power with w luxman, I paid more than that and i am happy with the purchase, $499 is a great deal, I think they only have 2 pairs left...
They aren't super efficient, so you wouldn't want to power them with a 20w amp if you want loud speakers, but 50x50 works well... They are very clean sounding and on the warm side of the spectrum, a very tame tweeter but still crisp and clear, great for most types of music, I don't use a sub with them and run the full range, they do the job well...
My set and the luxman 505u are back in their boxes right now, since selling my business I packed them up until I find a new place for them, I am thinking I will set them up in the kitchen at the lake house this spring...
