So I knew I needed to include a transparent high class amp to drive and test these phones. But Mary would divorce me if I proposed buying yet another expensive headphone amp. Instead I found a solution: Build one instead. The process has proved to be very rewarding in all respects. Let me tell you about it here.

I've seen some reports that the Stax 007 MkII (the "Omegas") sound a bit bassy and dull, but I don't have that reaction with the KGSS amp and a superior DAC. My precious Stax is clearly missing something in the bass department and I wanted to see if I could transfuse the slam of the Audeze into the Stax and have the best of both worlds.
