Yes I have heard the Overdrive SE DAC is a very nice DAC indeed. Not sure it is quite there yet in the uber competitive lower upper class of to name just a few Lampi, Berkeley, Meitner, Bricasti, MSB, dCS and it looks as if the DirectStream has poked its heard into there as well into this prestigious group. I know there are others this is small list but listed it to name the main charterers imo. Good to see your grass routes approach to the brands development which is meant as a compliment. I wish I knew more about the transport side of things. Looks like I have some work to do for sure. I very much appreciate the feedback. Correct me if I am wrong but I would assume any improvement I make in the transport area will provide benefits to any / all of the above mentioned DACS. With this group mentioned above do you really think their USB implementation is not good enough and really needs an off ramp? I have no doubt the off ramp will offer improvement but these are some pretty serious, engineering driven companies that seem to have paid decent attention to their USB's inputs but I am happy to always learn more from those that know much more than I. The transport/computer side of things is sort of a blur for me as evidence by my just using JPlay, a killer USB cable and JRiver in a plain old HP i5 Desktop. Would love to hear and learn more...Thanks
