Do you let the turntable spin when putting down record and attach the clamp.

To bad nobody makes a DD table with an adequate suspension and vacuum clamping with a platter thick enough to keep the cartridge away from the motor

Obviously you know nothing about reference Direct Drive turntables. Some of them are suspended like Luxman PD-444, some have vacuum pump and specially designed platter like Victor TT-801 and others.

If someone really need suspended DD they could buy isonoe feet here.

Some reference superheavy direct drive have built-in springs like this. 

What DD do you have in mind when you post bad things about DD in general?

If your turntable is delt-drive you can damage it this way.

If it’s Direct Drive you can’t damage it, and you can change record and add/remove disc stabilizer on top of the record on the fly (with spinning platter if you like).

I press the stop button each time I change record. I put my disc stabilizer on the spinning platter (after I turn it on, not before). But I use ONLY direct drive turntables.
