Is a Linn Sondek LP12/Lingo/Ekos with a Cirkus update, the last turntable I’ll ever buy?

@fstein  Perhaps think about upgradeability as a way to minimize audio nervosa..because one does NOT have to constantly trade or sell the table that is not upgradeable. You can stick with the same platform ( the LP12) and not have to fret about what it is that you are getting next! Easy,lol.

Saburo-In the last few days I’ve watched several videos on the LP 12. It didn’t look that hard to me.

@saburo  Setting up an LP12 is probably no more difficult than a number of other high end tables. The issue is that, at least IME, a basic set up isn't really going to get you 100% of what the table can accomplish. Best to leave the set up to someone who has experience with this...and luckily there are still a number of very good 'fettler's' around.
OP, you spoke to one of the better 'fettler's' around in Thomas OK...did you not believe that his ability would add to the final result of how the table performs?

If I had only one turntable to buy and live with for the rest of my life it would be a new Technics. They are more speed stable than most 'high end' audio turntables and also really low colorations due to vibration. IMO/IME their biggest weaknesses are the rubber platter pad (easily replaced) and the arm (although compared to many high end audio arms the Technics arm is no slouch).
