Preamp mods/Why capacitors?

I have a Threshold FET 2 preamp. Very nice, but clearly old - 15 years or so. It has been suggested that it could benefit from upgrading the capacitors. It seems that nearly all amp/preamp upgrades and tweeks I see involve the capacitors. Why is that? Are some just that much better? Do they tend to wear out over time? Is larger typicaly better? I'm not an engineer by training, but am curious about this.

This has been talked almost to death at some sites. I suggest you go to the audioasylum DIY forum and do a search under "capacitor". No need to reinvent the wheel here.

The classic thought on the subject dating from 1980 by Messrs. Jung and Marsh is here: www.Capacitors.com/pickcap/pickcap.htm
