Which cone's or platforms have helped?

All this talk about resonance transfer. Has anyone taken the time to think about it? If you're transferring the ever so slight resonance out, what about the big vibrations that you're transferring in? Footsteps or subwoofer vibrations are alot more than any resonance you're trying to transfer out. It's not real difficult. There are no one-way valves on resonance or virbration transfer.

Well designed platforms take care of the internal and external vibrations, since they do NOT work like a valve.
His platforms do not distinguish between the two forms of vibrations, but efficiently rid the component of internal as well as external vibrations.

Read what Kevin of Silent Running has to say about it:


A movement or vibration creates friction in the module and this produces heat. Heat is used to effect and change the darometer of the compound, in a pre-calculated manner dependent on weight. As vibrations pass through module after module, their amplitude gradually decreases until it is dissipated entirely. This is what makes the isoBASE such a highly effective isolation device.

Ken's NEUANCE shelves are an attractive, very affordable, easy-to-use system to isolate CDPs, especially. No change in spectral tilt, but trememdous improvement in clarity and coherence of low-midlevel source components. After the dramatic improvements on an old Rotel I had to get a pair for my EMC-1 (44 lbs) and Aleph P pre (35 lbs). These massively built components may not benefit as dramatically from the Neuane, but then again their resolving abilities should allow perception of even subtle improvements, so I use 'em there, too!

Get one of these racks and be done with it. You don't need any cones or other isolation devices under your components. Just place them on the shelf of the rack. It is also the best looking rack on the market. Alvin at Grand Prix is a pleasure to speak to. http://www.grandprixaudio.com/

Hi, Sean, I was trying to say that you posted the thread. Neglected to say that it was Ken who did the actual recommendation. It was great to have Ken take the time to post and good to give credit where credit is due.
Maybe Tekunda is right about the "one-way" effect of spikes. When my washing machine comes on, the floors shake and so does the rack, even through the spikes.
I would says spikes are used to provide RIGID coupling of speakers to the floor. It would take an accelerometer to measure vibrations with and without spikes to really know if they are being attenuated by spikes.
The Lack and Neuance concept appears to be to stop vibration transfer through the platform. So vibrations from the CDP go into the shelf and stop. Vibrations from the floor go into the shelf and stop. That's how I understand the concept. Whether is works or not should be easy to measure with an accelerometer.
