How many times is this video going to be posted? Here's the bottom line: take a $200 DAC and then swap out the cheap power supply with a high quality linear one. Notice any difference in the sound? You almost certainly will. Next, if the DAC uses socketed op amps, swap them out for good discrete op amps. Hear any more difference in the sound? Again, you almost certainly will. There is a lot more to the quality of a DAC than just the chip itself. The chip, how it is implemented in the circuit, the power supply, the output stage are all huge factors.
The DAC Scam - Almost everyone believes the hype
Over many decades I have owned my share of multi-thousand dollar dacs.My current is my Audio Alchemy DDP-1 + PS 5, which I have owned for ~ 4 years. I have made many changes to my system, including cables and it has shined a light on every one, so I tend to agree with the YTV . Your thoughts?
