confused about equipment racks

I have been considering either a commercial or a DIY rack for my components.
The problem is do you isolate or couple?
I'm good with speaker spikes which couple the speaker to the house.
But what about a CD player? Isolate? Couple to something massive? Why do I read about Maple butcher block?
I've read about people who swear tennis balls are good. Others use hockey pucks or handball balls, whole or cut in half.
Steel shot, lead shot, cat litter and a host of 'custom' ($$$$) products to fill tubing.
All sorts of weird (to me) theories about resonance / damping / microphonics and related phenom.

Any opinions or stuff I can READ to try to straighten this out. Please, not too much advertiser hyperbole.

thanks in advance::

Hi Magfan. The below thread has a lot of discussion of a DIY "flexi" rack design, with some discussion of different materials. John

Hi.

This is the best article I know of, per your request to read something: 1995 Stereophile's "Bad Vibes" article http://www.stereophile.com/reference/52/index.html

You would probably benefit from reading it a few times over several days to let all the info sink in and start putting together a "strategy".

I hope it helps.

Home-Depot sells a number of 1.25-1.5" OD tubing in various decors (brass,silver and PVC with different cosmetics),whuch can be loaded up with your damping material of choice.This will hide any tarnishing of the metallic up-rights and adds significantly to the mass/rigidity of the rack.

Thanks for inputs::
Seems I've got some reading to do.
So far, however, I 'lean' towards all thread for the uprights, nothing hollow since I'm not going to open THAT can of worms!

I may experiment with tubing later. My fill idea is to use expanding foam with steel shot. The foam will increase the rigidity of the tube while the steel adds mass.
