What isolation feet under your amp with great result?

Before isolating the amplifier from the vibrations coming off the speakers... isolate the speakers vibrating, your source, your floor, your walls, your rack/stand holding all of your equipment.

Saying that, getting the energy into (springs for example) will require some planning, especially if your system is sitting on a substrate, being the materials under your floor, which may be somewhat absorbent already. Concrete is ideal as its rather unyielding compared to peer an beam, wooden floors. However mass loading under wood can drive a higher percentage of energy into an isolation system.

Townshend of UK and Solid Tech of Sweden are two good sources for products and information as to why I am suggesting the speaker isolation before electronics for return on investment.

Right now both of my legs are the same length. Would one of you care to stretch one out by explaining just how isolation feet in a solid state amp does anything but part you from your money? The number of products seeking to answer problems that are not there and those willing to buy are a source of never ending amazement to me.

Perhaps you must read a little about vibrations and resonance before  boasting about knowledge and ignorance?

What amaze me is the horse calm speech with blinders, explaining to all others, why it is very useful to avoid being afraid or even scammed...

As a suspected "naysayer" I am compelled to challenge your assertion and ask whether you have measurements to substantiate your claim?  Have you opened this belief up to study and confirmation by independent observers?  Did you pay a significant upcharge for a pair of perfectly matched legs and would it really affect performance if one leg was say, 1/8th inch shorter or longer?  I owe it to this forum to protect unsuspecting readers from being deceived by those making unsubstantiated claims of perfectly matched legs.
