Interesting, do you have a build thread for the pre? Thanks!

You can build it with $40 in parts (my op amp version). For power supply, you can go crazy like I did. But a simple ifi wall wart (or any Wal Wart with a few Amps of current output) will do. It has to be clean. I learned the hard way. 

The schematic is here:
