vibration control

Paperw8,
I think that what is ridiculous is making the comments you make without having tried any of these devices. It isn't always possible to explain why something works, but that doesn't mean that it doesn't work. That isn't to say that there isn't good science behind some of these devices.
Anyway, why don't you give it a try? You may have a pleasant surprise.

It is useful to use isolation devices under every component. There are countless types, they all sound different, and you will definately have to experiment to decide what works for you. Start with cheap things like small myrtle wood blocks. There are so many good things. The brass cones by Mapleshade are also very good.

I don't believe in magic either Paperw8, and I have tried several tweaks that yielded little or no positive result for me. It is really too bad that we need to waste sometimes substantial amounts of money to find out that it was for naught. I have had sidesteps as well as backsteps with amps, speakers etc., but we were talking specifically about isolation/vibration devies here, and I was saying that I have had very positive results in some cases.
The most extreme case for me was Starsound platforms underneath my speakers. Expensive, but worth every cent.
