Dave, I've had the BAT for about 7 years and other than getting the transport/laser overhauled at year 5, its been an excellent unit mechanically. As with all things which have tubes, tube selection makes a difference. I've never bought into the upgrades. Too much money for my ears. It throws a huge soundstage and is very detailed, without being at all bright or rolled off. The only thing I have ever found lacking in it, and this is a minor nit, probably more about me that the unit, is that I still prefer my old Cal Alpha DAC for vocal and instrumental sound. A bit more mid-range emphasis which I find pleasant (and a bit more forward in prospective - not in tone). I keep thinking I aught to upgrade, but then I read all of the reviews and user comments about whats available and go back to listening to music on the old stuff. If you can get a newer BAT, or an older one which has had the laser overhauled, they sure are priced right in comparison to the other stuff I'm seeing on the 'Gon.
