Component isolation


Let’s say you’re going to add isolation feet to a component with no moving parts, such as a preamp, phono stage, DAC, amp, tuner, etc. 

Which one is most critical to the extent would get your attention first?

I'm sure as time goes on some of those Tunees will be coming here to share their experiences. When they do you can ask them directly. As for me I'm here to help them get started on their journey and design tools, where they take it is up to their own passions bdp24. While I listened with both JGH and HP we spent our time tuning and often making fun of the HEA. So my take on my friends may have also been different from yours.

as always, appreciating your points of view even if they do differ from my experiences

>>>>>Actually, that statement is patently false. I know what you’re thinking, that the sound musical instruments make and the sound speakers make is acoustic vibration. But that is not what the audio signal is. The audio signal in CD players, turntable tonearm wires, preamps, amplifiers, cables is not acoustic vibration or any vibration. It’s electromagnetic waves, an entirely different animal. The problem is that audio signal, the electromagnetic waves, no matter where that signal is in the audio chain, is subject to external vibration - acoustic, seismic, transformer vibration, capacitor vibration, footfall, etc. a common example is acoustic feedback. The cabinet resonance and or acoustic waves from the speakers affecting the audio components via the air and or floor and producing distortion. That’s why isolating components and speakers improves the sound. Hel-loo! 
We hear electricity not original sound, a helpless imitation of reality. Don't fool yourself. Well, that was wrong - fool yourself and keep it that way. But Michael is right, you some guys don't get it. Passing signal causes vibrations that change it, that's the problem. Dealing with external vibrations is easy by comparison.
Thanks Geoofkait for the clear explanation...But Geoff how my stones or crystals act on that loop? I sense that these stones "filtrates" in some way but I dont understand exactly how and why... Do you have an answer?

>>>>Crystals almost always work via resonance control. Even when they are used around AC circuits or wall outlets, or on circuit breaker panels, they work via vibration control/absorption. Other notable locations for crystals that demonstrate this concept are on room walls and glass windows and doors p, wherever a sound pressure peak occurs, and on top of Tube Traps. Crystals’ principle of operation is due to their atoms acting like mass-on-springs, albeit teeny tiny masses and teeny tiny springs, thus converting external energy to heat.
