Run Balanced and RCA at the same time?

Hey Beemer...that's exactly what I want to do...run 15 ft balanced from LS 25 to ARC vt100 then run 15 ft single ended to my xover. The cables will probably be different.....

WireWorld-Jenna-Acoustic Zen to the power amp(balanced) and then my older 330 MIT rca to the crossover..sound ok??

Thanks guys...because I would like to use a 15 foot IC I have been reading that balanced cables are better then single ended in that lenght. Thats the only reason I am considering the balanced cables.
Beemer, the crossover for the RS 1-B's has a low frequency level knob so I think I am safe with the base volumn.

Thanks Sean & Beemer....before I run my VT 100 amp into the mid/tweeter panels directly I will add the cap (not sure where((I am a techno dummy)). I will have my dealer do it. But some people say put the cap in the vt 100....some say add an out-cable box with the cap in it.....some say put the cap in the ls 25 pre amp. What are your thoughts?
