Mostly these kinds of threads tell me more about what wealthy hobbyists think about their money than what they think about equipment.

DAC 'Scam' Vid
https://www.youtube.com/watch?v=7Sg1nYLmLCw
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.
