Excellent turntables with threaded spindles ?

Aside from those tables with vacuum hold down and outer rings, what fine turntables are available that have threaded spindles which permit the use of a screw on record clamp ? Thanks very much.
SME Tables have this...
Well Tempered tables have threaded spindles.
Depending on your tastes there are many, including the above-mentioned tables, Oracle Delphi's, all current VPI's (though some also use a peripheral ring to hold down the records)...and others, but I haven't heard them.
Opus88, if your objective is to ensure excellent connnecton of LP to platter and flattening of the LP on the platter, a screw-on clamp is not the only solution. My Walker Audio Proscenium turntable uses a smooth spindle and yet has among the most effective record clamping of any turntable out there. The secret is in the design of the clamp, not whether the spindle is threaded or smooth.

Dear Rushton, Thank you for the info. I thought that Walker was using screw-on clamp. Basically, they use a heavy weight clamp to flatened the record, don't they?
KAB modded Technics 1200.
I agree with Rushton, a spindle does not need to be threaded to have an effective clamping system. I own a Basis 2500 Diamond Signature, which has a unique no-thread clamp design as well. I actually prefer it over my old VPI HW-19 mk IV which had a threaded clamp on device.

John/Rushton, how can a non threaded clamp be as effective as a threaded one?

I have a warped 200gram LP that requires a LOT of pressure to clamp down. With a regular clamp I would probably damage the bearing trying to get the LPs= flat.

For me, I would avoid using screw on record clamp at all cost. The reason is that the spindle is usually an extension of the bearing shaft with has direct contact to the ball bearing/thrust pad....If using a screw on record clamp on the TT, the grinding noise from the ball bearing/thrust pad will transmit throught the bearing shaft to the spindle then to the clamp, LP and noise will be pick-up by the cartridge. The 'screw on record clamp' is not well thought design. A record weight or damper is a better choice.
But do record weights effectively deal with warped lps, especially those with pinch warp ?
For those who've asked for some further details, the Walker Audio clamp uses an internal Delrin bushing. (I've not seen the Basis design, which may be similar.) The bushing fits inside the clamp via threads on the outside of the bushing, but it is smooth on the inside and slides over the smooth unthreaded spindle. As one tightens the clamp, the bushing is pulled up into the clamp forcing it to compress around the smooth spindle. As the bushing tightens onto the spindle, the clamp's outer circumference is pulled down onto the surface of the LP, flattening the LP against the platter. With this configuration, as much pressure can be applied against the outer circumference of the record label as any threaded spindle clamping arrangement. As with any clamp, some judgement is required for how tight to pull everything together. The clamp is as rapid to apply and remove and it works as a single integrated unit. The clamp also is quite heavy, being a massive unit of machined brass.

Edle, you raise a good theoretical objection to clamps that attach to the spindle. In my listening with VPI, SME, Walker Audio and other turntables that use this approach, I can't say that I've ever actually heard the downside you postulate.


You raise a valid point, but as usual it's all about implementation. The design and build quality of the bearing will have a major impact on the costs vs. benefits of a screw-on clamp.

On my old HK/Rabco ST-7, bearing noise and intra-plinth vibration levels are so high that any record clamp, even a light weight Michell, seriously degrades the sound. The spindle isn't threaded but if it were I suspect the table could be the poster child for your theory: it would probably go from noisy to unlistenable. ;-)

OTOH, all Teres tables include a screw-on clamp (there's another one for Opus88's list). The bearing design and BQ are such that clamping the record firmly makes a significant sonic improvement, and there is no noise that can be attributed to bearing friction. The table is effectively free of bearing noise and silent grooves are exactly that, even with the gain controls turned well above safe listening levels.

Assuming a well made bearing, intra-vinyl resonances from stylus/groove friction are VASTLY greater than bearing noise. Clamping to a massive bearing can provide an effective pathway to evacuate and eventually damp certain frequencies, to the betterment of the sound.

A record weight or damper may or may not perform better, again depending on implementation, but IME bearing noise is not necessarily a reason to avoid threaded clamps. The devil's in the details, as usual.


IME a center weight or clamp won't do much for a bad pinch warp. Dish warps can often be flattened, even when playing the concave side, but pinch warps require a vacuum platter or periphery ring.

In truth, if one's arm and cartridge are reasonably good trackers, warp-flattening is not the main reason to use a hold-down device. The main benefit of weights, clamps, periphery rings and (I suspect) vacuum hold-down is to provide evacuation paths for and dampening of intra-vinyl resonances.

The drop in noise floor and improved low level detail and clarity from weights, clamps and rings is much more audible than any flattening of the record - at least IME.
Add the Kuzma Stabi to those tables with threaded clamps.

Edle, if your theory of vibration transmission with threaded clamps is true (and it may be per Dougdeacon's observation), why would it not also apply to clamps which grip the spindle in some fashion to secure hold down? To be effective on a smooth spindle, this must be a tight grip and that would still promote transmission if I have any understanding of physics. The only way around this would be a heavy weight which would not need a tight coupling, and that might introduce micro chatter.
Yes, the theory will apply to your mentioned method too. I used to have a light weight Michell LP clamp...I used it a few times and sold it. It was not worth my time.
Music Hall MMF 7 comes with one from the factory, also a really excellent table for very resonable cost, you can find many favorable reviews on it.
Doug: Your observation on the Teres clamp and its application sounds encouraging. I am interested also in how effective The Galibier Anvil is in providing positive results regarding the turntable/record synergy. Can anyone out there offer any helpful comments on this ?
