Does this mean that my tonearm and cartridge are not properly (acoustically) decoupled from the top plinth and this negatively influences the sound?

Could / should this be improved and if yes, how? I have put a rubber washer at the arm base, but it did not seem to make any real difference. I wonder whether the bearing is too tightly screwed on the top plinth...

Any advice from other Xerxes owners, please?
I'm not sure which component you are referring to when you say the 'top plinth' as I would say there is the outer plinth and the top plate or chassis. Either way it is inevitable that tapping them whilst playing a record will result in a thump sound coming through the speakers. As you know the outer chassis is only decoupled from the plinth by Roksan's rubber 'blobs' and this only offer a modicum of isolation. If tapping the top plate then one is, in essence, effectively tapping the chassis directly and as this is directly coupled to the arm base and the platter this is bound to be heard as transmitted vibration (vibration very much greater than the stylus is generating). I wouldn't recommend placing anything compliant between the arm base and the chassis either. Unfortunately, I also wouldn't recommend changing the AC motor for the DC Origin Live - but you've already done that .
