Vintage DD turntables. Are we living dangerously?

Lew,
I suspect a massive pod on spikes threaded into the bottom of the pod might be better than bolted to a base/shelf. I understand what you're saying, I don't think it's necessarily true.
**Whatever happens to the tonearm, from whatever source of spurious energy of any kind at all, should also "happen" to the platter/bearing at the same point in time.**

"Whatever" covers a lot of ground. Are you tracking through a seismic event, perhaps your dog bumped your TT stand? I chose sound pressure waves because it's the logical choice for a non-suspended table. In that case I think it might be better if the pod and platter were not joined at the hip. Spurious energy would more likely to be transmitted and propagated from one to the other by their common joining. This is a bad thing, not good.

Once again, having the platter, arm and motor moving in unison is the law of suspended tables. Even those with a fixed motor seem to get half decent results sometimes. Throw out the suspension and what specifically are you talking about with spurious energy? Why is it better having them joined? Methinks it's worse, with greater potential for degradation.

We're not

Richardkrebs,
This is not a freewheeling platter running at speed. It's constrained by the string.
If you measure as suggested, I think you'll find zero movement of pod or platter.

I think that we have done this subject to death.
Let's agree to differ and move on to some other topic?

BTW, apologies for misspelling your moniker. Big fingers, small keyboard.

Cheers.

"Whatever" means normal disturbances that occur in the typical playback setting, not f**king seismic events or dog accidents or children running into the tt or etc.

This has NOTHING to do with suspended turntables. Nothing nothing nothing. I don't like suspended turntables, as a rule. What you are thinking of is that in a suspended turntable the tonearm and bearing/platter MUST respond in unison, else you have all sorts of problems. But I am not in any way, shape, or form talking about suspended tt's per se. Are we clear?

It's hard enough to make the point without these exaggerations.

Lewm,
Okay, take away the movement in unison aspect of a suspension, and exactly what are these extraneous sources of energy?
Why is it better if they are joined by a plinth or whatever, than planted on the base?
Don't tell me they will act in unison to some undefined energy and cancel affects, because they won't. I'm saying it's more likely negative affects will be increased.

A plinth or chassis is a logical design for a commercial table, but it is also good at transmitting extraneous energy between platter and arm. I can't understand why you think this is desirable. Heavy pods coupled to a heavy base is more likely to resist this negative energy, depending on design.
