I want to connect my source to somewhere 35ft away for headphone enjoyment, what is the best way to do it?
 
1.  Coax / Optical seems to be best but I'll need to buy another DAC (I need the current DAC where it is)
 
2.  USB - will also need another USB DAC, and from some research anything over 15ft requires an active extension which has some sort of signal boosting, and I wonder if that will introduce jitter
 
3.  RCA - Simplest setup cuz I can use my current DAC but common sense tells me this probably have the biggest potential for signal degradation.  Say if I get the premium cable from monoprice, will it be much worse than the above 2 options?

Good quality RCA cables should be fine...otherwise coax is probably your best bet.  I honestly doubt RCA cables would degrade the signal at all over 35 feet though.

Thanks.  I'll start with RCA cables.  One day when I have an extra DAC I'll compare it with coax and optical
