Plinth ideas for DENON PD-80 DD turntable

Genesis,

The Motor in the DP75 is considerably smaller in the DP75 and the control system simpler, both are excellent machines.

The DP75 and DP80 are not suitable for use with a copper mat as the platters are two layer spring loaded the weight of the copper cause the springs to sag too much.

The DP7000 is also a magnificent table - have made many of these into GrooveMaster Vintage Direct DP7

Lyra in Japan has 5 of these made by us. 3 of them with the SAT tonearm

Good Listening

Thanks for clarifying. From the specs they seem to be identical. I’ve opened them but not side by side. Yes it’s a spring loaded platter. Have been using the copper on it for a good while with no ill effects. 

Thanks for the link, Peter
The lighter mass platter mat (400-900g) would better than 1.8kg Micro ?

Dear chakster, There are shops who make all kinds of stuff from
acrylic. The most use laser cutting. For my former Technics SH-
10 B 4 plinth I ordered  3 arm boards for 3 different arms.
They use acrylic plates which can be glued together for whatever
dimensions. But you need to proved them with schematics. They
cost about 100 euro each.  You can use the arm board from
your Denon as example so the only thing you need to do is 
provide them with  the spindle -hole distance for each tonearm. 

I own a Dp80. It is perhaps too simple to say that the platter is spring loaded. The platter is two concentric pieces,an inner piece that is about the size of the record label or a little wider in diameter, and an  outer which goes all the way out to the periphery. The inner and outer platters are linked by flexible thin metal fasteners that act sort of like a spring to decouple the two sectors . This was Denon’s way of isolating the platter from the bearing, since the playing surface of the LP is almost entirely supported by the outer platter. So if you used a solid platter mat, like a copper one, the dissociation between the two pieces of the platter would be abrogated. I don’t actually know whether that would be so terrible, because the mat doesn’t couple to the bearing in any case. I would not hesitate to try a copper platter mat or some other solid mat, if that is of interest.
