Still need to get that hard drive and drive to rip my CD;s, but listening to all the great music on my server through this OSDE is blowing my mind. I don't even have my Vandy Quatro's yet. This is all through the Treo and Ayre AX7e (waiting on my AX5/20 to get here in a few weeks) and WOW>.. This is nearly the best I've ever heard for a DAC. I recently heard the DCS stack and it was special and also the Bricasi DAC with all Tidal gear. I didn't know the other components, but I'd put my OSDE up against both of them and it won't embarrass itself. When I had the AX5 in my system it took it to levels beyond which means that I haven't heard the best from the DAC yet. It just keeps getting things right and I want to thank Steve for making this unit and supporting it like he does. I'm a convert guys. I never was going to buy from a small maker, but I'm glad I did and I hope that he is training someone to take over from him eventually. Genius is a word I'd use. I think I have auditioned nearly every DAC that's been talked about in this thread as well as others, so I think I have a decent reference. Thanks again to Matt who started this thread as I'd never have heard about Empirical otherwise.
