. . . I don't know of any well recognized manufacturer that has made the claims you have suggested.
Me neither but, hey, why let facts spoil a good argument?
beppe:
a usb power supply should not be necessary at all with well designed usb dac/converters
But a well-designed USB DAC pre-supposes a decent local PSU. Taking power from the bus is fine for non-critical devices but not so fine for others such as modest - let alone "well designed" - scanners, printers and so on. Do you complain about 3.5" USB drives needing their own PSUs?
The very first thing that i read about usb was how dirty and weak is the power on the usb port ...
Exactly. See above.
And the usb receiver reclocks the signal already
The USB protocol wouldn't work without a clock at both ends.
