Plinth ideas for DENON PD-80 DD turntable

While my pair of Victor TT-101 still sleeping in the storage, i decided to buy another Flying Saucer.

The DENON DP-80, vintageknob always have nice images and info about rare stuff...

On that page you see DP-80 with DA-401 tonearm for hich compliance cartridges (i have this tonesm NOS). It could be an interesting project, it was hard to resist ...

The question is the Plinth for this Denon DP-80.
The original DK-300 plinth is an option, but searching for something better i found this one.

Custom made plinth is always an option and i have superb Audio-Technica AT-616 pneumatic insulators to use under the plinth.

But what do you guys using with your Denon PD-80 ?

P.S. some companies now producing even an iron cast plinth and graphite plinth, i have no access to graphite, but iron cast here is cheap to make a custom plinth.

...but honestly i don’t care about it, can’t remember when i’ve been using a rubber mat last time, normally i replace them with my favorite SAEC SS-300 (lightweight) or heavy Micro Seiki CU-180(or superheavy CU-500) depends on the turntable torque and platter.
@chakster  I have the SS-300 too, and use it on most TTs, preferring it to rubber. But there's an issue with the DP-80. The platter is in two parts, isolated from each other, to keep all bearing/motor noise from reaching the inner part where the LP/stylus do their thing — it's quite different from the split-platter on an LP12 and others where the 2 parts are in direct hard contact with each other. 

Both the 300 and CU-180 interfere with the platter's design. Though the DP80 has ample torque for the CU-180, it interferes the most. I suggest the SS-300 is better suited: it has a cut-out on the underside at the edge, so it doesn't contact the outer platter at all.

You're right, just tried it. It is true that the bottom side of the SS-300 is slightly smaller in diameter than my Denon rubber mat. So this must be the right mat for DP-80 

I've seen people using it with CU-180 too, but i thought about weight on that spring denon platter. Maybe this is a wrong mat for DP-80. 

Has anyone tried this ?

I use ss300 on my TT101. If the dp80 was in regular use, I’d buy an ss300 for it,too.
I’ve been in Tokyo this whole time, visiting our son. When I get back home I’ll check the condition of the Dp80 platter.

Chakster  - I use the Boston mat on my DP80 it works great.
Another mat that needs investigating is the Acromat from funk firm.
As far as using CU mats on the DP80 i don't think its a good idea they are too heavy for the spring suspended inner platter.

Good Listening

@pbnaudio thanks Peter, i'm gonna try The Mat from Sakura Systems, it's in my wantlist. 

BTW: how do you lubricate DP-80 motor ?
