The USB input for the DAC, power supply, headphone out and DAC are the differences. I would guess both DACs measure pretty well which is why I would like to see the comparison. Perhaps there is a big difference in sound, but I would speculate it would be hard to tell in an objective test. --

Well Ralph that is precisely why I would like to see the measurements as I believe there is a correlation as to how sources measure and their sound. The Sabre has a "reputation" as a good DAC but I have no idea how the two DAC circuits compare to each other and to something like a Touch and Transp
