I have got about 150 hours on the ART9 now, it continues to amaze..
My AR PH 6 was just breaking in when I felt the need to upgrade from SoundSmith in the same price range as the ART. I kept track of hours on the ART up to 100 and now just enjoy the music. The thing I find is I don't hear the equipment, just the 3d images hanging out there from wall to wall. I recently installed a new record mat from Herbie's and I am in awe. I had a friend over recently, when I got up to flip the record he exclaimed " holy crap, that's a record?" anybody on the fence on this should jump on in.
@oregonpapa what was the belt upgrade you mentioned early on in the thread?
