Shawn is building a tube stage to test with the step up transformers today. It will be pretty simple, built on a Seduction chassis. One triode of a 6DJ8 will function as a CCS'd gain stage and the other triode will be configured as a CCS'd hybrid shunt regulator - sort of "Seduction power supply and tubes meets Paramount driver stage". Should give ample gain, well over the typical 2V CD player output. Hopefully we'll have it up and running this afternoon.

I plan to try a few different tube output stages, with the idea of coming up with one that is reasonably priced and fairly easy to build, and one that is an all out finished piece to go in a high res music server.
