Looking forward to hearing this with my HD650s. Not that I need another headphone amp, but I'll never hear one of these unless I build it. BTW, I highly recommend the Aoyue 937 soldering station, if you need a soldering iron. Available for $60 shipped on eBay. Do yourself a favor and get a temp-controlled iron, some de-soldering braid, and a flux pen before you start the kit.
wildstyleI have a Chemtronics no-clean pen and not sure about the wicking braid, but it any brand is fine. I'd also recommend the Aoyue or Haako brass sponge tip cleaner, a small wire cutter and a wire stripper tool.
