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.

They're also made of fancy materials - both metals and insulation. There is no reason why it should be different IMHO. Purity of metal still applies since impurity reside between crystals while insulation material directly affects capacitance and dielectric absorption.
