Wrong again. More and more of your better dacs don’t use usb and more and more are adding i2s and Ethernet. USB is flawed, never meant to provide good sq. I did all of that 10 years ago or more with usb dacs and all the gimmicky reclockers, femto clocks, offramp devices, and others.
Talk about noise, you probably have a streamer/computer in your room which are much noisier than most dacs. Go back and read the reviews of the DS mk1 dac, nobody complained about noise. There is no mk iii dac, just the mkii which is noisy.
The only other dac that bettered the mk1 was the dcs at multiple times the cost with their Ethernet connection. I preferred the DS mk1 over the briscati, Berkeley, msb offerings, up to around $20k price range.
