That’ll be me when I hear the sound. Ye ol’ monty. Thanks tomic601...... I found this interesting and educational on the subject of isolation: https://www.andrehvac.com/blog/vibration-control-products/difference-vibration-isolation-vibration-d... |
There are a lot of principles in common. Skyscrapers for example use almost the same damping system as is used for speakers. In both cases the idea is a mass damps resonant behavior. Springs don't damp at all but they do isolate allowing vibrations to be damped or dissipated within the component itself. This can result in some resonant behavior that colors the sound. Townshend adds a very specific small amount of damping to greatly reduce this resonant coloring of tone. Same thing happens even within the turntable. Part of the problem is isolation to prevent environmental vibrations from getting into the turntable. Another part is preventing vibrations generated within the turntable itself from getting into the environment, because this sets up ringing which smears and colors sounds even more. A third aspect is to dissipate vibrations generated within the component, essentially converting them into heat energy. All three need to be done, and as if that isn't hard enough they need to be done equally with frequencies across the audio band. Or the sound becomes colored. The crazy part is all these things don't just happen in turntables. They happen in everything. Even in speaker cables, vibration control is a factor. |
Don't know what issue you are trying to resolve but after many tries with my system the one device that solved all the issues were the Solid-Tech feet of silence. They're fairly economical too at $500 for 4 - at least when I ordered them. Put those babies underneath the feet of your table and be amazed. |
Having owned both SRA and Critical Mass platforms nothing beats my Vibraplane. I still loved my critical mass platforms and used them under my Joule Electa Destiny’s were they served me well. I have owned the following tables, SME 30/2, kuzma xl4, TW AC3, micro Seiki rx1500fvg and a Transrotor Rondino. All benefited from the vibraplane now in its 16th year in my system. |
