I don’t have any problems with my DS (well one… I don’t get to listen to it enough but have a question related to using a usb cable that I could not see an answer to after searching. My understanding is that after the dac does its initial handshake with the server, it doesn’t require the server’s 5V power. That seems to be the case with my server as I can swap to the un-powered output on the server and everything works fine. The thing I’d like to find out is does the DS have a logic board before the DAC process that (after handshaking with the DS) turns off the 5v via a relay etc?
The reason I ask is that there is a considerable price difference in dual headed usb cables v’s cables that are separated (signal and power) but share the same A and B plugs. I definitely want to get rid of the power side after handshake (at the USB B end in particular) by either 1) switching it off/unplugging it (5v side) or 2) using a dual headed cable [more expensive ] or 3) using a dual cable sharing the A USB plugs; IF the DS “disconnects” from the server’s power supply after handshake. ie no current flowing through the power side of the cable interfering with the signal side; and therefore making the use of a dual headed cable unnecessary?
If a tech person can tell us whether or not the DS does isolate (open circuit ) the 5v that would be great.
