My first amp, and first time soldering, here it is, my CMoy:

Those headphones are HD580, anyone notice anything different about them? I also built a replacement cable, it is 4 runs of teflon coated 22awg silver/copper wire in Litz configuration with Neutrik 1/4" TRS.
I got bored the other night, so finished stuffing my Mint. Not cased or split yet, and I want to take the gain down when I get some different resistors (currently at 11, want it around 4), but it works, has only 1-2mV DC offset, and makes the E2c's sound much better. I don't have any good 9v batteries (though I had one but its down to about 4.5v, really scared me when I tested DC offset and it was several hundred mV, but I ghetto rigged it with a spare Fortron 300 watt ATX PSU, running the mint off the 12v rail, and it is fine. Actually sounds better than I was expecting.

So, what does the future hold? Right now, I have a PCB for a Gilmore Dynalo, ordered PCBs for a Millet Hybrid, hope to build an M^3 sometime soon, and beyond that, who knows?

Small change to the portable, still have to case the Mint.
