isolation

It can help a lot!
In my opinion, (as I don't use lp's), the CD player is the place to start.

The difference under my Marantz SA14 SACD player was monumental.

Yes it does. Although with a really good stand, it is my experience that additional isolation is not as big a deal. Vibration, especially on anything that has moving parts, is an absolute soundkiller. If a mechanism is rotating on the horizontal plane, and there are vertical nodes interfering with that, it changes the distance, and also slews the frequency. I have measure my system with various acceleromters, and the changes (or lack thereof) are pretty amazing. One thing about this... you CAN actually subjectively measure the effects of isolation/coupling devices using white or pink noise through your speaker with a broadband accelerometer. The effects, however, are both rack and equipment specific from what I have bothered to measure. I heard the most difference of anything by using rollerblocks under speakers and subwoofers, but turntables and cd transports seem to be very sensitve to coupling issues as well.

Audiolifestyle,
Consider taking advantage of the ninety day trial period from Herbiesaudiolab.com for Tenderfeet, or Iso-Cups with two different ball options, under CD player.
Even within the first few minutes, you will clearly hear the benefits for your favorite recordings.
Very reasonably priced approach, which has been as effective (or, more effective) than many other choices I have tried.
Every footer/base enables a somewhat different sound from a component, and Herbie's creations are easy to implement, and musically rewarding.
Once you hear what happens with your first component, you will probably want to try something under every component.
By the way, the Big Fat Black Dots under speakers are ridiculously good, for the money.

I have heard isolation make "changes" in performance on transports, preamplifiers, and power conditioners. Don't ask me to explain it. I have not tried isolation on amplifiers yet.

Unfortunately most of the non-platform isolation devices I tried hurt the sound. I said "most" since some did actually improve the sound.

I think it is more than just component specific. Nobody ever mentions the rack and shelf material being used but I think this would have to enter into the equation. Meaning an isolation device that works on a component on one rack may give different results on the same component on a different rack. Platform devices may be more consistent than non-platform devices. Just my opinion at this point. Not something I have fully explored.

Vibration is everywhere and comes from various sources. It could be from the ground, it could be airborne, it could be from the components themselves. I used to work for a high tech company and every single piece of equipment in every lab sits on some type of vibration table. It could be a 300lb slab of rock, a sand box, or it could be a air-based or mechanical-based vibration table.

I had a similar experience as Don s described. A friend of mine had tried several platforms and ended up with a 300lb slab under his tube amp. He purchased some Grand Prix Audio stands last year. They were made of some light carbon fiber material with stell tube legs. When I held one in my hand, I was thinking how something like that could be good for an amp. Well, after we put the amp on the stand, all of our eyes were ready to pop out. There were 4 of us in the room, and we went back and forth several times.

I would also echo Don s' point that different devices have different effects. I've always placed my SS amp on a BrightStar base, which is essentially a sandbox. After my recent amp change, I noticed the sound was slightly "lifeless". I think the sand was actually draining some of that top energy. The problem was solved after I swapped out the sandbox for a SolidTech amp stand.

As for racks, don't underestimate the effect. I've been using sand-filled SolidSteel and Lovan Sovereign modular stands, which I had considered doing a good job with vibration. Recently I switched over to a SolidTech Reference component stand after hearing what the Grand Prix stand was doing for my friend's system. I had always thought that my big projection TV was the culprit for my "flat" 2-dimensional soundstage. But with the new stand, I now have a 3-dimensional soundstage despite the TV sitting somewhat in between the speakers. (I'm sure if I remove the TV, it would sound even better.)
