There are hi-end DACs that use proprietary DSP and proprietary converters. They just aren't cheap, because they can't leverage on high volume components. These would include, I believe, some DCS and DAD products. Someone who has these products might provide model numbers.
The most critical DSP processing involves the filtering required to deal with the 44.1 sample rate. If you feed the DAC bit perfect 44.1/16 then you will need good DSP in the DAC. If you use a separate box and upsample to a higher multiple you can get by with much less critical DSP in the DAC, and good DSP software is available pretty much for free if you have a computer based transport. However, you will have to deal with all the other problems/opportunities of computer audio, e.g. noise and jitter problems.
