SP10mk2: OMA Graphite plinth vs.Dobbins plinth

Dear @lewm : The original SOTA mat has not that " felt like material ". The SOTA mat was on sale as an after market mat and goes glued ( self glued. ) to any TT platter, in that way the mat is part of the TT platter and not changeable: it keeps fixed there for ever. Another very good characteristic is that its spindle center hole is small diameter enough for the spindle form part of the TT/MAT part. The mat has no " play " around the spindle even you have to push it with care but enough pressure to install it.. It helps to damps the metal spindle too. Was very good thinking item other than its undisclosed build blend material. Recomended.

Dear @ferrari275: """  a pure Copper platter mat's tonal characteristics are superior in.........................................................................................

aluminum alloy..........I recall it was thin anemic sounding, not at all musical ...."""


Tonal/anemic characteristics?, I can't understand why we are looking for a kind of sound in the TT mat when what we have to look is for an " inert /non resonant " mat that can damped and don't interfere coloring the cartridge signal.. Metal is resonant no matters its weigth and unfortunatelly resonances/vibrations colors the audio signal and steel is no different. In the aluminum AT the LP is " running "  on vacuum and the SOTA is non-metal ones. Normally metal is a bad material in TT/tonearms/cartridges and the like. As less metal in a home audio system as better its quality performance levels. No, we can't disappears metal material from audio items  and in some specific items is need it.

Dear @downunder :  """  any other mat I have tried... """

Try to found out the ATs and original SOTAs and test it vs what you already have, I'm sure that even your P3 will be an improvement.

Dear @sbank : What I'm trying to say is that both: the original SOTA and ATs are even better for those TTs, that's all.

Good that you are enjoying your system day by day experiences.

Dear @downunder : Sp-10s or those japanese massive old designs as MS needs not those kind of metal mats ( other than blocking EMI if that’s a real problem in the TT. ).

The best mat for any TT is the original SOTA mat, yes the one TT manufacturer. .
I said " the original " because the designer of that mat gone from SOTA and never disclose the SOTA mat blend build materials and after that the other SOTA mats that were builded and even copy after market ones are way different.

Other than that great mat as @pryso posted the AT 666EX and the AT 665BX. Both better than any of the ones named here. Its vacuum hold down function makes real impprovements, I wiish my SOTA could came with that function.

Btw, @sbank that Vient Nam gentleman works truly fine, good. Now, I'm thinking to change the the metal drivers in my speakers bor a less resonance/more inert metal driver holder. Thank's for share that link. Every day is a learning day !.
