Isolation Platforms under Line / Power Conditioners ..any thoughts ?


I am a Harmonic Resolution fan and have my equipment on them with very good results. Is it worth the expense of putting one of these under an 81 lbs line conditioner ? Would it really make any sonic improvement ? Let me know and thank you in advance.

The only way to know for sure is to try it.
With that said I have large brass Audio Points under my two Isolation Transformers (over 100 pounds each) and there is improvement.
Yes I think you will hear improvement however I'm not sure whats the best product to use.
Why not try isolating the power conditioner with Super Stiff Springs? Springs are very cost effective.

isolation and resonance control

I haven't heard any component, power conditioner/regenerator or otherwise whose performance is unaffected by resonance/vibration control.  In my experience, any time you can mitigate resonance/vibration you realize an improvement in sound.  I have Black Diamond Racing puck/cones under my PS Audio Premier regenerator.

Agree with geoffkait that you don't have to use a fancy (read expensive) audio tweak.  There are materials available at Lowes/Home Depot that can yield a desirable effect.

IMHO  ALWAYS do what you can to reduce resonance/vibration in your components.  This includes modifications to the interior of a component as well the exterior.  
Look at Symposium Ultra Stealth top for best sound i have 2 Audience 6TSSDOX units on Symposium custom amp stands .
