Completely forgot about this thread.
Tried to order an amp about five/six years ago...
What has this got to do with tracking him down and why would someone need to? Where he lives is no mystery.
No mystery to semi-close friend's like you maybe.
But with his lack of responses for so long it's easy to assume that he could be dead, or moved away with a new email address.
Or building the DAP/Radio/DAC/Amp of all DAP/Radio/DAC/Amps!
Regardless, we can all hope he's all right. I know there are those who had high expectations and severe disappointments, so there is some tempering there.
I still use and marvel at this SuperMacro IV and Supermicro, especially the latter with one AA.....
He always told me that if some of the products that came after his hit the market had been in place, he would not have made amps. He just wanted a good sounding amp and to provide that for other people.
My favorite is still the Supermacro III and the Micro. The Mini was his favorite and was the first to use the famed high output opamp (I can't think of the number right now but very well known).
I'd still be happy if he emailed me and said my SuperMini is ready. I liked the SuperMacro III that I had. Not sure why I sold it...
Was it the AD8616? That's the "tube-alike" one he offered that I ordered with the SuperMini.
I remember now, it was the 8397. That is what Xin used in the Supermini and the Supermini was always his first love for an amp. If I ever get back up to Oregon I will look Xin up, most likely just drop in on him as he doesn't answer the phone. Too bad, good memories from back in 2005 and 2006. I still have all my Xin amps, a few Reference amps, that sound excellent, and others.
