Direct Drive vs. Idler Drive vs. Belt drive

Sdrsdrsdr,

I am using the Ortofon 309, also with a heavy weight for taking up the Neumanns. And the SME 3012 (I), first version.

Dear Halcro,
I still love my belt driven tables. As I am „walking“ from one to the other I recently found out that the two mentioned favorites attract me most. Nevertheless the AS equipped Brinkmann Anniversary  and the Victor are very close to the Denon. I regard the big motor of the Denon, the 4cm aluminum chassis as well as the platter (which I improved by a 1000 USD ceramic overlay) running by the new Furutech connectors as very stable and quiet. The AS cartridge is a good match.

Caeles II, the Micro and the Continuum are not far away as well.

"Even if the platter replaced with thicker and heavier one those guys always add copper mat on top of it, just like the latest Technics SP-10R."

The Technics Sp10R's main platter was designed to be used in combination with a platter mat, like the supplied factory rubber mat or an aftermarket metal based mat (ie. Copper, gunmetal, stainless steel, delrin ect.)
As shown in the poster link, that Sp10R platter was photographed in the "nude" without a mat installed.  The material section at the top is a brass alloy, and not Copper. 

@ferrari275 i think you’re quoting me, not neonknight :)

But you’re right, the idea is sandwich of materials(to block EMI effect if there is any or that none existing noise from the bearing that every DD hater mentioning here), not just heavy platter made from one material. Do you know anyone who keep using rubber mat on Technics ? I do not own SP10R, but i owned SP 10 mkII and Micro Seiki CU-500 mat is a perfect match, the platter of SP-10R is flat and slightly different on the edge. Brass alloy is cheaper than gunmetal. Copper is cheaper than gunmetal too, but this copper matt from artisan fidelity looks very nice.

@chakster
After re-reading the above, I think you are right!  :)

Everyone I know with either an Sp10Mk3 or Sp10R is using an aftermarket platter mat of some type and not the supplied rubber mat. 

Agreed, either the Micro Seiki CU180 or more rare CU500 Gunmetal Copper alloy mats would be ideal for the job.
In this country (US) Gunmetal alloy is more generally expensive and harder to obtain than pure Copper, but in many countries it is the opposite.  I own a Gunmetal Copper Micro Seiki CU-180 which I have compared to the Artisan Fidelity pure Copper Universal platter mat which I use sometimes on the Kuzma Xl DC, and they are similar, but the later can give some recordings a touch more weight and "body" if you will, to the sound.  My thoughts here are it may be because gunmetal contains 88% Copper, 10% Zinc and 2% Zinc (est.) while the pure Copper mat does not contain the additional metal alloys.
