It's just that I think you'll find most people here would find a multi-thousand dollar DAC a complete waste of money.
Yeah, this DSP box probably has a DAC that measures better than a $10 CD player, but what can be measured, and what can be heard are two different things.
Any modern DAC will far outperform what the human ear can detect. An ADC/DAC pair will pass a band-limited signal without any audible change, and virtually no measurable change. The only place where they man be some noise creping into the system will be in the analog input/output, but that will likely be more than 90 dB below the signal, even further down when using balanced connectors.
