Thoughts On Turntable Clamps And Weights

FWIW, Kenwood made a peripheral ring back in the early 80s for the L07D. If you use it, there’s a special setting on the power supply/motor control module so the servo then compensates for the added inertial mass. Yet the ring seems to slightly downgrade the SQ of the turntable. Darkens or closes in the sonics, slightly.

@lewm 'Darkness' makes me think of an absence of treble - yet some of the most musical of TT, IMO, can also be described this way. Like the Nottingham Analogue Dais.

Every time I've made a big improvement to my system, it's involved a loss of high frequency hash. The sound just becomes smoother and more natural, less 'hifi'.

So I'm wondering about your use of the term 'darkens'. Could it be that the Kenwood ring reduces HF distortion? Or are you using the term differently?

@pindac  I would not try to re-invent the wheel. The carbon face air bearings from New Way are near perfect IMO, and they are cheaper to buy than to make. Again, IMO.

@terry9 Thank you for directing me toward these products.

I am looking at the Recommended Brands 13mm ID Bush Bearing. 

The Bush is looking like it will require a shaft close to 22mm ID which I assume will need to be designed to enable the potting of the part and allow for a air supply to be connected.

These are dimensions that I feel confident of being not too far from from the alternative dimensions to be selected.

I am keen to pass on the link and receive the feedback from the Engineer.

Thanks for reporting back. I think you correctly assessed the info… light weight clamp. I know my TT would not do well with a heavy… perhaps even a light weight.
