Building plinths for quality DD tables?


Nearly every reference I've read on building a plinth for a Technics SP-10 series table assumes high mass is needed, similar to Garrard, Lenco, etc. rim drive tables. Yet, the SP10 does not display the same noise and vibration problems as a rim drive. So why would a similar massive plinth be needed? Did this idea originate with the two Obsidian plinth models offered by Technics?

I'm in preliminary design of a plinth for my SP-10 Mk2A and a friend who also owns an SP-10 recommends a minimal plinth - basically a platform to bolt underneath the table, along with a tower to mount the tonearm. He lives a great distance away so I cannot audition the performance of his set up. So, does anyone have experience with a minimum plinth design rather than the more typical 40-50 pound plinth? If a minimal plinth would work as well, it would be much simpler to build.

If you have experience with plinth building for SP-10, Denon, Kenwood/Trio, etc., I would appreciate your input.

Thanx, Pryso

Impulseh2, I have an early IOj and it does best in an Ikeda FR64x rather than a new Ikeda 407, OTOH my Denon 103R performs best in the Ikeda. I also great great results with the IO in an SMEV, but it is a bit fiddly to install. I might try it one day in my Triplanar VII, but not intuitive with the fixed wiring for both and having to use conectors.
