The video mentions that the Holo May has a better SNR than the Mola Mola maybe you need to watch it again. There's lots of info out there but if you want to buy a designer product at 2-3x the price go for it.
IMHO DAC chips are best because they are more accurate and real, R2R will give you that lazy valve sound, but if that's your thing go for it.
Real live music doesn't sound like vinyl.
