This is a great sounding amp that I'm not needing anymore. I would trade for a Stax amp (+ negotiable cash), OR just sell the amp outright. For a cash sale I'd like $350. I havent had the amp too long (I bought it new) and it has low hours on the tubes. Very low hours. The chassis is in great condition. Its a nice amp and I think the price is good for this quality of amp.
I want to mention that this tube amp works very well with low impeadance headhones (Sony's, Grado's, and AT's) which is not true of all tube headphone amps. I talked about compatibility issues Pete Millet himself and found his advice to be true in use (while I still had dynamic headphones that needed an amp) and the HA-1 does not mind low impeadance at all.
