I'm using Tele EF806S and a gold pin 7308 too. We're using some cables made here in the lab from some long crystal copper wire I had around that is now unobtanium for signal cold, some Alpha teflon insulated solid core wire for signal hot, and some Belden braided shield, with Neutrik Pro-Fi RCA plugs. I'm coming off the single ended output, running into a new line stage we are working on. Not quite ready to release the details on that, except that I'm pretty pleased with the results.
