Did not bother to view the video.
My journey started with my iPhone hooked up through an adapter to a Pass Labs Aleph P. I found it almost unsuitable for even background music. When I went to a Devialet 200 set up with its built-in DAC, I could now listen to digital for background music. The next step was to the built-in DAC in a Vinnie Rossi L2S preamp which enabled me to actually listen to digital and enjoy it. My current DAC has virtually become a replacement for my analog system since the sound quality is so good and the convenience is no contest.
As some people have mentioned but I would like to emphasize, the analog portion of the digital-to-analog-converter is extraordinarily important.
