If you really want to go down that rabbit hole, there is a right way to do it. Record something on a robust analog medium. Cassette is fine. The quality doesn't greatly matter. Then digitize this recording into a computer file at 44.1 kHz, 48 kHz, and maybe even 96 kHz (but that's a waste). I'm going to assume your digitizer is crappy, so digitize at double the desired frequency and then downsample by half. Then you take an oscilloscope and start picking apart the analog recording vs. the reconstructed analog output from the DAC. Extra points if you re-digitize, import into Python w/the Scipy stack, and start calculating quantitative metrics. Blind A/B tests don't do it, but this will. The only real confounder could be the ADC, but only if you have a horrible one. Generally speaking analog -> digital via sampling is an easier thing to do than digital -> analog. All that said, my ears seriously enjoy this. I'm going to go listen some more, and if this gets dropped again I think I'm in for another. Props to Aune, this is a great product!
