Long unbalanced RCA or long USB cable?

In my listening room it's not feasible to put my computer, which I stream from, close to the audio rack.  So what's the best option, 15 foot USB to the DAC in audio rack or short USB at computer with 15 foot unbalanced RCA cables to the preamp?  Or am I just over thinking it.  Presently I'm running a fifteen foot USB to the DAC which is placed with all the other components.  I'm getting no dropouts but there is so much talk about long USB cables not being good for sound I'm not sure which way to go.

It'll be the debate of "it's only '0's and '1's"
Although USB has a very reliable CRC check, USB audio devices use isochronous communication which has no hardware error-check. Which means that the device itself has to be able to recover from occasional errors.
If you don't have the crappiest USB cable (no need for overpriced cables) and don't go over 5m it shouldn't be a problem (if there is you'll clearly hear dropouts).
You could also use shorter cables with a USB hub in between (you can only chain 5 hubs).
