Turntable plinths?

[mushroomgod]

out of curiosity what (if any) are the general characteristics of glass/wood/mdf/acrilic turntable plinths?

Well...not being a turntable owner for a few years now I will have a punt at answering your question. Apart from the obvious looks, its really down to resonance. The lower the resonance characteristic the better. In order of best to worse it probably goes something like....MDF, Wood, Acrylic and Glass. Possibly a swap around between MDF and Wood but that would depend on the type of Wood being used.

HTH.

Check 'Young's Modulus' on Google. Damping will play a part as well. I once made a plinth for a Thorens deck back in the 1970s, it was made using heavy duty marine ply lined with lead sheet. It was brilliant, until that is a heavy goods vehicle went past the house when the arm and cartridge decided to walk across the record... Moving the unit then made it dance whenever I walked aceoss the floor or there was good bass content when instead it attempted earth orbit. What a steep learning curve!

Light but very rigid, open supports are best.

The old Sound Organisation and Target spiked turntable tables were very good. (No long made alas.) There were also wall mounted versions for those with hopeless floors.

Rega and Project still make wall-mounted turntable supports.

Keep things as rigid and minimal as possible to offer as direct as possible a path for the support/TT combination to lose unwanted vibrational energy quickly.

The other approach is to 'mass' things up as much as possible with tiers upon tiers of granite/marble/sorbothane feet/spikes/special laminates/acrylic/glass/metal and heaven only knows what else.

I wonder if you mean platters rather than plinths?, as I have never seen a glass plinth ..........
