Hi, everyone is discussing about plinths. The bigger the better. Why such neurosis? Plinths are pretty to look at but do they really give much sonic improvement? Plinths could add colorations to the sound --> is that what you want?

Single plinth for multiple table/motors
I recently saw a picture in another thread about a Sony TTS-8000 which got me thinking. Would it be possible and/or reasonable to build a single plinth (in the manner of CLD a la Lenco "Home Despot" tables or similar to the construct of Alberporter's recent Technics SP-10 Mk2 and Mk3 efforts) which would accept a "top plate", to which the table/motor was affixed, similar to the way some of these tables have armboards to switch arms.
I have a couple of table/motors that I would like to re-plinth, and a couple of arms which I would like to use. If I could affix the table to the "plinth top plate", and then seat the "plinth top plate" within a larger "outer plinth", my thought is that a slight change in material construction between the top plate and the larger outer plinth would have the effect of reducing overall plinth resonance. It would also allow me to build a single large "outer plinth" and cheaper sub-plinths for each table so that I could play around with several others. Theoretically, once I build a basic plinth, I could add more TTs/motors, or simply change from one TT to another at some point in the future, building only the sub-plinth in order to make it work. I would not need to build (or get built) a whole new plinth with sets of armboards each time I wanted to change things.
Any thoughts as to whether this is a stupid idea? Or any thoughts about methods of attaching the sub-plinth (the one carrying the table) to a larger "outer plinth" would be helpful. I was almost thinking that using something like bicycle wheel quick-release assemblies which would clamp on the bottom would be one way to be able to change them quickly and efficiently, and to allow a little bit of flexibility in how hard one clamps down (when I tested headshell screw tightness, I was surprised to discover some changes are audible).
