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.

What type of "Line Source" do you have? Mine sounds insane! No one ever believes me when I explain what it will do. Until they hear it..... Ha ha.Then they always get that "Confused" look on their mugs!
"IF", your using the USB cable that lets, "Makes", the signal bypass all, "Sound Enhancement" software and second party software? Then that should be all you need.  "It's the USB cable with the (Square-ish) USB connector on one end ". 
They either work or they don't?....
 A year ago I was playing with a new DAC/Streamer I purchased. For some reason it didn't like my wifi. That companies "Support" explained to me then that the "USB" might be a better option for me. AND they also explained that using an "USB" with that squarish connector and your laptop/PC, was the only way to get "Just the signal", With no data compression, filtering or sound enhancement program changing the audio and etc. "That squarish" connector is read by your laptop and once found thinks it is a "Printer" I think. Or something like that. And it clears a path for just the audio file in it's entirety.  Thus bypassing all the crap.
    It is a very reputable company "By the way", as well. And I used that set-up for a time in my shop.
