Nude Turntable Project


I could not fit the whole story in this Forum so have had to add it to my System Page.
I am attempting to hear if a 'naked' DD turntable can sound as good as Raul claims.

Gary,
I'm sure you're right about damping the 'cage' and I intend to do so if....and after....I have eliminated the 'source' of the feedback?
Incidentally....I tried the 'bungee cord' treatment to no effect :-(
My thoughts are....that even if I dampen the 'cage' successfully WITHOUT treating the cause.....there is still transference of energy which is manifesting itself in some ways?
Banquo,
I agree with Gary. I don't want a suspended (bouncy) table.
With the Victors supported on the outer cage......it is very easy to induce 'movement' if the supports are not executed correctly? And that 'movement' is magnified enormously because of the lever-arm of the metal cover in relation to its connection with the platter.
I've experimented with rubber and insulating materials and whilst the bass may seem to improve.....the highs are badly affected?
Evidently, I didn't express myself clearly, but let me try again.

The springs don't go directly beneath the turntable cage but rather below whatever platform the tt sits on, in my case a sandbox. The weight of the tt + platform results in the spring having a certain frequency at which it moves. My sandbox and tt weighed around 150 lbs and there was certainly no bounciness to the system. I take it no one believes one can turn a non-suspended table to a suspended one by changing the type of platform the tt rests on. Or am I missing something?

At any rate, Halcro, you mentioned an issue with low frequencies affecting the tt-101 and I thought this might be worth a shot, since it theoretically at least allows one control over just that.

But if one is like Gary and you "don't have any issues that require amelioration" then I'm truly envious :).
What is the cage made of? I always thought that if I could find one of these tables to play with that it might be a good idea to have a disc cut out of plate, .125" to .250", of the same material that the chosen pod material is to attach to the bottom of the cage. This should fix the flimsy section that the feet are attached too and should help sink any resonance.
Sorry Banquo,
I didn't get what you were suggesting?
A Minus K stand is the obvious solution to my concerns and I am investigating that possibility?
The problem with that for me however.....is that the increased load of the Minus K plus a top plate of slate that I may need.....will simply increase the stresses in the cantilevered shelf which are the cause of the problems in the first place?
it might be a good idea to have a disc cut out of plate
Not a bad idea Ecir......not necessarily of the same material though?
A dissimilar material such as 'wood' may be even better?
I think I'll try a few experiments based on this?
Thanks.
