I've been using my Dynavector XX2 MKII for two years, daily with no problems. It's sound balanced, rich, tons of detail and yet never analytical, I would estimate about 1200 hours. tracks anything, and has the ability to cut through noise thats amazing. has hooked me on Dynas for ever. I would pass on the original XX2 though, to me not as fast or resolving as the MKII.
BTW, Ordered a new VPI 17F cleaner today. Here when i get back from FL on the 6th.
