Five meters should be no problem, and you can probably drive 10 meters with little or no audible effect.
That's theory (with a healthy dose of safety margin of course), based on the same calculations that say Seduction is good for 1, or at best 2 meters of ordinary interconnect. If anyone has direct experience, I hope they will post it - data always trumps theory.
"Nobody believes the calculation except the person who did it. Everybody believes the experiment except the person who did it." A little engineering folk wisdom :^)
