Once some critical parts upgrades are made to the AN DAC kits, I think that the USB to SPDIF converter is the next critical performance 'bottleneck' for a Computer/USB based digital source.
I would be interested in an effort in choosing optimum usb to spdif converter for use with the AN kit DACs. I recognize that it may come down to personal preferences. An asychronous approach may be the best, but reviews suggest that a more ideal implementaion of the 'adaptive' approach used by the Hagerman unit currently offered with the kits might also be good. See the Stereophile review if the Halide Design Bridge - the difference between the Bridge and the Stello U2 was subtle. A recent 'converter comparo' in Positive Feedback (http://www.positive-feedback.com/Issue51/usb_converters.htm) also suggest this. I would certainly be open to modification of the Hagerman, if it is a worthy modification platform (in other words, if that would result in sound compretitive with other potentially built-in options like the U2, EVO, etc.).

Bob
