I have a vk-75 on order, and I sold my vt 100 mk II. the ARC was great, but I really did not want to pay $839 when the tubes needed replacing. I'm told the BAT will only be around $400, and the tubes last a minimum of four years (unit off when not in use). Also, how cool is the BAT open architecture? I can't wait. I have mixed thoughts on the SE. Of course, I'd prefer that unit, but I don't know that without a side-by-side comparison, I ever notice any difference. Tubes are more costly also. The stereophile f/u review was too short to really help with this $2500 decision.
