Concrete might be excellent. I recently saw a Kenwood L07D. It's plinth is made in part of a very dense particulate material, much like concrete. (The plinth is further damped by metal and wood layers.) By all accounts, the L07D is VERY quiet, so I assume the plinth "works". But this makes shipping of an L07D a nightmare, because that concrete-like stuff may crumble if it receives a blunt force blow. I would think also it might be difficult to make a precision fit with concrete, because does it not shrink while drying? But in principle, concrete would be an interesting choice and would probably work well. I see that you propose to start with pre-formed slabs of concrete. Can it be "worked" to accept the SP10 without crumbling? Anyway, it's a cheap experiment.
Technics SP-10 Tonearm Pod instead of Plinth/Base
Trawling through the Audiogon forums for information on a suitable Plinth for a Technics SP-10, I came across a post by Raul.
Instead of putting the SP-10 in a plinth, he just put the TT on three feet and then had constructed a separate base that only housed the tonearm. (I haven't seen a pic of this BTW)
Following on from Raul's 'Thinking outside the square' approach, I thought I might be able to buy, or have made, a stand-alone 'pod' or rectangular tonearm plinth that could sit along side the SP-10. Has anyone seen something like this that I could buy 'off-the-shelf'?
The advantage of this is that the tonearm is decoupled from the TT and therefore distanced from any vibrations generated by the TT.
A down side is getting the right geometry for the tonearm in relation to the distance from the spindle; and then keeping the pod in the right spot.
If this is all too hard, I might still go with a plinth. I notice an E-Bay seller in Taiwan is offering a Teak plinth cut for the SP-10. Anyone bought one of those?
All comments welcomed!
