On the draining of resonance.....


I have read of the importance of controlling resonance in components that contain motors and transformers. This seems to involve placing isolation points or bearings under components to attract or "drain away" micro vibrations, I suppose, of resonating frequencies. Ok--say this works, but hasn't the resonance already occurred as it is being drained away through the bottom of the chassis? I get the idea of isolating out airborne vibrations carried by the rack, stand, plinth, block, etc, but......really?

Basement. We had problems with unstable fill on the building site so our basement slab now sits on top of $26,000 worth of crushed rocks. My turntable sounds great. Highly recommended. LOL

KN, I'd like to think you could get off you hands and knees......If you had a solid stand for your turntable, you know there wouldn't be any vibrations coming up through the floor--only through the air. Question is, would the energy in the air cause vibration in a low stand. Probably, yes, depending on size of room, size of speakers and proximity, subwoofer or not, etc, but you could cancel that with a final isolation between turntable and stand. It may even sound better--you never know.
I think part of the reason some people say a 4" wood block sounds better than a 2" thick wood block is because the greater mass as a part of the equipment-spike-block system resists being affected by external vibration to a greater degree than the smaller mass block. Independent of any potential benefit imparted by greater mass/material as sink for internal vibration.

I have a rather unremarkable rack that I am working to improve rather than replace because of unique aesthetic match to the room. Ultimately I will migrate the turntable to the rack with a set up similar to what I have recommended above.

Good luck with your resonance and vibration control efforts.

Hello fellow Audio Nirvana seekers...I just looked at what was being said about resonance control after experiencing some incredible results in my system.  All I have to say is that  I'm completely blown away...contact  Robert at Star Sound Tech. http://starsoundtechnologies.com/

Robert is very knowledgeable on this subject...the best thing is that you can try the products for 30 days in home and then return them for a full refund if you don't like them.  I could lay down all the audiophile terms to yawl but I'd be wasting my time - TRY THEM ...You have nothing to lose...TONY  

Recently Art Dudley, a few issues back in a post I think called '3 rules' discussed resonance. He basically said draining efforts via spikes etc just makes the speaker front vibrate more. He said no spikes and use felt pads on everything. Check it out.
