Unfortunately some people really can't hear differences in cables, DACs and especially power amplifiers.
If you can good luck to you!
Everything else is clickbait.
DAC 'Scam' Vid

The TL:DW is that any well made Dac should not be more than $200 and anything above that doesn't sound any better since they all use similar cheap chips to do the D/A conversion. Anything above $200 for a DAC is basically snake oil and theres no improvement in sonics.
Appreciate your insights.
