I'm B.S. on applied math and statistics. The difference between me and MBA that I shuffle numbers in my head on flight and MBA in computer or calculator.
I know how much all electronic parts worth and therefore I don't need to get this information from manufacturer. The figures I wrote for DAC is very-very maximum of what you can possible think of building. So considering profit and labor DAC can't possibly be more than $5k and for these $5k in pro-audio you get HUGE variety of settings and adjustments and with multiple inputs for integrating more than one digital source.
If such $32k DAC offers that, than it's actual NEW price is fair to be at or near $5k.
