Is there a qulaity DAC that has USB and coaxial.

Jafox has a sound approach here, if you'll forgive them pun. Sonicweld Diverter does an excellent job as well.

Now that you mention your budget, perhaps PS Audio PWD could be a possibility. Please note, though, that it's a full sized component in width and depth at around 17". Not sure if form factor is an issue as opposed to physically smaller units such as those mentioned above.
