I think that if you are seriously considering a B52 you should also consider the Eddie Current Balancing Act. It is priced below the B52 and to my ears sounds significantly better with all my personal cans (K340, K701, HD650) as well as the HD800 and LCD-2 which I have heard on other systems. Also, my Balancing Act is from the initial run and uses 307A tubes. I have heard all of the aforementioned cans except the K701 on BAs using AD1s and PX4s.
