Can I use 3 pin DMX cables instead of XLR?

I am putting together a reasonably priced system after a remodel. I have the option of using balanced inputs/ outputs. I already have 3 pin DMX cables that were too short for a friend who does lighting.  The DMX cables are 110 ohms and the XLRs are 75.  My friend said the DMXs have lower capacitenance and should be better.  Is that true?  I love music but I am just at the beginning of learning about equipment and I did not find much on the net that wasnt more concerned with lighting.  I trust my friend and all but I would appreciate some community input too.  Thanks!
