DAC 'Scam' Vid

@mitch2 I've read great things about the AC line. Interested in your opinion once you've had a chance to hear it. 

I went from a $15K DAC to a $2800 DAC and that was a huge conic improvement. I am trying to buy the same $2800 DAC for another system.

The authors of these videos seem to forget that a DAC is more than just the DA conversion, it is also the first pre-pre-amp in your analogue chain. Similar to a photo stage. The other thing is isolation to noise. Better designed DACs are immune to upstream (and even internal) noise. Beyond this there are finer points like the clock… anyway, it’s always more than it looks like at first glance. 

Seems to me the benefits of higher dollar DACs are found in the analog conversion side and the power supply circuit.

Those who can, do, those who can’t teach or complain.
