I think the first question you would have to ask yourself is "How much am I willing to spend?" Relative to the cost of your source material, preamp, amplifier, and speakers, do you really want to spend as much as $895 for something like the Audiophilleo? I am currently using a modified HiFace, into a budget-level Beresford DAC. I'm please with the results and doubt adding a $900 USB/S/PDIF converter would greatly improve the system as a whole. As long as the converter supports up to 24bit/192k resolutions and has independent reclocking circuitry, you should be set. To get any more granular would require a great deal of downstream upgrades for proper upgrade justification.
To more directly address your question, I would say that you are most certainly picking the wrong priority. I say this, of course, without knowledge of your system as a whole.
