You might try a California Audio Labs Tercet, which has coax input and output (but you'd need a Toslink converter). What's your objection to simply buying a transport and DAC (separately) -- they can still be done under your price point, and done quite well by Bel Canto, CAL, or Audio Alchemy. Most DAC's have multiple digital inputs, so simply use the coax or balanced connection between the transport and DAC, and use the Toslink connection to the computer.
I know that's not exactly what you asked for, but I think it's a reasonable consideration.
