Well like any big expensive piece kit you need to own it for a while before you find the flaws and I'm afraid the Teton's flaws are fatal at least to me.
It is the best sounding amplifier for hd800's and lcd-X's by a mile but finding quiet tubes for it is pretty much mission impossible. The 2 tubes I did have that were quiet are no more cause they went up like a firework. They were my flagship tubes as well so bye bye $600.
My favorite purchase has slowly become my worst audio nightmare so I think it is a good lesson to let the placebo effect wear off on people. 20+ tubes, $2000, 0 quiet. Came from brent jesse, andy bowman and people who have a good reputation here on head-fi.
I honestly don't know what I'm going to do. Todd said I owned the peak/volcano for too long to be returned and I still have not sold that in 6 months... half priced.
