I'm selling a Xin Supermini-III which is not in the greatest condition but which works fine. My ears are terrible and I've admitted to myself that source, amplification, etc. don't really change the experience for me enough to warrant keeping the gadgets.
I got this amp in perfect shape several years ago from another Head-Fi member. I used it for a while but one day tripped over my headphone cable and chipped a bit off the audio out jack. However, the amp works fine (I had to bend in the gold ground pin a bit since it wasn't making reliable contact--now it's working fine).
The main opamp is the AD8397 with a bypassed buffer socket. I will include a short, handmade interconnect suitable for connecting to an ipod or computer. I will not include the AAA batteries or a wall socket adapter. All the switches (gain, crossfeed, etc.) are in the amp, so no worries there, you can use the audio options just fine. As far as I know, this amp was not upgraded with Supermini-IV featured by Dr. Xin before I got it.
