Hey,
I could have been one of the folks on Oade board hyping up this A/D possibilty. I've been corresponding w/the owner of AOS off and on for the past few months. I'd sent him some recordings i've made for him to demo. At that time, he mentioned that he was making good progess on the design. I'll try to follow up w/him on more specifics. I have not been able to purchase any of his gear to date, however, I am intrigued to try out the Piccolo DAC which he now has available w/coax (inputs).
