oh good but do you think the balanced input could be better than the unbalanced one?
I'll use it with cable to amp near tens of power cable and usb cable behind the pc...
What do you think?
Given my background in Pro Audio I always prefer XLR connections out of habit. I don't think RCA is a problem given the short distance you'll be using on your desk. I have a lot of components (amps, DACs) on my desk with lots of cables, RCA is still not a problem. If in doubt you can try to avoid running power and RCA cables in parallel or at least separate them a bit.
If you're getting the G103 I'd vote for the RCA ('S') version, its more versatile in a home setting. Its also easier and cheaper to get adaptor cables to RCA. If you get the G109 I'd recommend the P version as it offers both XLR and RCA inputs (though unfortunately no input selection switch).
