List Of Diy Headphone Amps

I just had a thought: we need a list of current do-it-yourself headphone amplifiers. So here it is. I'll be updating when someone alerts me to new amps or amps that I have missed. Now, since there is a very large amount of circuit designs available, I'll only be listing available kits and PCB (if you want a circuit design only, you should check headwize).

And what do you know? I just found a brand new design that came up yesterday (31/01/2011)!

Available as a kit (and sometimes as a PCB).

Available as a PCB.

Available as a group buy (hurry!)

Currently unavailable.

Uncertain (you might have to make the PCB yourself).
