The logical question here is why do you necessarily need a one-box solution that has digital inputs? For a comparable or lower price, you could have a separate DAC and use a good bang-for-the-buck CD or DVD player for the transport. Most DAC's have more than one input, so you could easily add an additional transport to the same DAC. That achieves the same thing that you want, with more flexibility (and more options, too).
I'm just suggesting an alternate way to view your options.
