I agree with John that you should keep the length as short as possible. With that said, I am currently running two of my tables with a 1.5M and a 2M (DIN to RCA) tonearm cable with excellent results.
I have almost always had at least a 1.5M or 2M tonearm cable somewhere on my system. Never a problem.
