Custom rack, isolation under platform vs component?


Hi all,

I build my own audio rack as pictured here:

 

I should have used wood that was thicker, as it is not super rigid. If I push on it, there is some wiggle. And if I apply some torque, there is some torsion. I believe if I bolt the platforms directly to the frame, and use the isolation under the components instead of the platform, the rack will be more rigid.

 

From your experience, do isolation feet work better under the platform, or the components?

Why do you need an isolation Device below most components.?. For turntables it makes sense. Otherwise does it really matter?

Maybe if you lived on top of a subway platform but then how can you possibly listen to anything if this happens

Thanks again for compliments.

 

@jumia I'm new to audio, but have some background in physics. From what I understand, vibration in the components can come through the ground from speakers, through the sound pressure waves in the air, and that internal components like transformers can also cause vibration. So even a solid state amplifier can end up vibrating due to these factors, isn't that accurate?
