Do stands make a difference for equipment?

Does the kind of stand you use make a difference, especially with components other than turntables? I realize how much difference a good stand can make for a TT, but does it make much of a difference for your preamp, CD player, and other front end units? How about amp stands? I'm trying to decide if it's worth upgrading my stand to something more robust, which means pending $$$. I currently use an old Target T5 stand, which is similar to the Solid Steel 3 series, and have just switched to a Sound Anchor stand for my amp. Since I switched amps at the same time, and the amp weights 200 lbs., I'm not going to AB it with my old stand.
Would love to hear what experiences you have had with different stands.

Thanks and good listening,
Mike
