At what distance are balanced XLR cables needed?

I've been looking for a new preamp for my 2 channel system, and I'm debating whether I need balanced inputs if I want to eventually connect it to my home theater processor. I plan on moving soon, so I can't say for sure what distance I would have between the two systems. My preamp options quickly dwindle if I require XLR cables.
