Prana Distribution

Well I would never buy a Semper Sonus.

Why would anyone want a turntable that whenever there is an issue the manufacturer goes on a public forum to cast aspersions - airing his dirty laundry in public so to speak.

Best to avoid issues like this - buy a different turntable - plenty out there without the aggro.

I also note that one member on this forum who purchased this turntable had multiple build quality issues and ultimately sent it back - 

All was well–the table sounded great (long REVIEW if you are interested). Except it wasn’t–there were a few lingering fit and finish issues which were not successfully resolved, all a byproduct of the pandemic and the harsh realities of global shipping, and they were bugging me. As an “early adopter” I anticipated a few bugs would need to be ironed out but despite lots of time, effort and good will on all sides, the problems remained. The TE-2 sounded great, but ultimately Paulo and I agreed that the table should go back to Portugal for replacement and upgrade of some key parts and then on to another client for further evaluation.

You moniker is misleading.

Your turntable is not an idler drive.

An idler turntable is when you have an idler wheel between the motor pulley and platter ( hence the name "idler" ).

According to your diagram on your website the Sempersonus drives the platter directly off the motor, the urethane wheel is the pulley.  This a rim drive turntable, albeit the inside rim of the platter.

And today you don’t really need an idler. Now you can get a motor to run at 150rpm, smoothly, silently, cheaply enough and you can switch speeds electronically.

You obviously have no idea how idler turntables work.

The pulley size determines the speed of the platter - the idler wheels are just a transfer function - you can run any size idler wheel and the speed doesn't change.

The idler wheel really is a low pass filter to reduce noise transfer from motor to platter. It has nothing to do with motor speed or platter speed.

I'm staggered at your lack of knowledge.
