Thanks guys..
The luxmans are really great. I have done some rebuilding to them thus far (KT88 conversion, new coupling caps, etc) The Zu's are also really a treat, and something I didnt expect to like as much as I do (I came from some B&W 804D2s). They are very quick and a very pure speaker. They are sensitive to poor quality stuff, and take a bit of fiddling with toe in, gap spacing, etc to get sounding their best. However, very rewarding and a great match for tubes given their high sensitivity.
