for the hd650 favoring voltage over current, it's simply that it represents a 300ohm or more load. it's the same with any high impedance headphone the hd650 is nothing special on its own.
about all the crap to improve usb, if people are really concerned about how good usb can be, then they wouldn't use usb in the first place. get a soundcard and a dac with a nice coax or some optical stuff, that's how you improve usb IMO.
now back to the odac, I have never heard noises from sources with it, when I did on some of the other DACs I got in my hands(cheap stuff for the most). so while it's nothing scientific, it's good enough for me to believe I don't need to "improve" my usb.
now if you go on the shiit topics, you see that several people heard noises, and using a wyrd or any nonsense stuff like that does seem to improve on noise for most of those cases.
I read it as bad computer usb(try to get an usb card for 20$, or if voltage is the problem, get a powered hub also for about 20$), or as the DAC being crap(change DAC instead of trying to turn a donkey into a race horse). on the shiit topic they prefer to read is as amazing wyrd.
take your pick, in a sense everybody's right.
I agree with you. I have never had any noise from the ODAC/O2 combo with any USBs. Once, there was no sound at all, but that turned out to be a shorted/burnt USB cable. Replacing it with another spare resolved the issue.
