If it helps, Fred_fred2004 made some circuit boards for the linked 12au7 design. I am currently waiting on the shipping since he is located in Australia but he is selling them at a great price and still has some left.    http://www.head-fi.org/t/664191/starving-student-pcbs/15#post_9503650...

How many do you have left roughly? I am looking to get into DIY but wanted to do some more reading first. Hmm one or two....

cool, thanks for that - didn't know about those drivers

I just got the Beyer dt770 80 ohms and just got a cheap xonar DG soundcard for 20 bucks on newegg (just looked it is 16 bucks). Unlike the DGX the DG has a dedicated headphone amp.    This is my first real jump into hi-fi and it has been great. You will for sure want to find some higher...
