*chuckle* What I am doing here is not putting the financial cart before the horse. After I have had the four pieces of tube gear (3 Macs and a Dynaco) restored, I'll put them on the market. If I get anything close to what they're worth, I'll should have enough money for a decent headphone amp. Which one, I can't say yet. It will probbably be silver and say "HeadAmp" on it.
Didn't you make Duggeh a Stax-to-XLR4 cable that matched the TakeT's peculiar pinout so he could test driving the H2s with a Stax amp? Whatever became of that, if Doug wrote about his findings, I didn't see it.
Interesting. I wonder if that "RCA out" is a loop or a preamp? I suspect the former, which would be of less use to me.
