@mijostyn You'll want to be careful using the vacuum system! I had a Sota Cosmos some years back that damaged the LP surface held against the platter pad. Dusting both sides before playing didn't fix it. Later, Sota changed the surface of the platter pad to be softer, which also changed the sound of the turntable. When I got our model 208 to sound better in every way I let the Cosmos go. For the record I've no idea how they handle this now.
You are incorrect about the speed stability of properly executed DD machines- there is a very good reason the Technics SP10MkIII holds a high value on eBay- its a performer and takes any belt drive machine to task. The new SP10R and SL1200G do too.
The reason that it 'was not enough to help them years ago' is due to misinformation and nothing more- I know, I fell victim to that same misinformation.
