How good is a fully upgraded Technics SL-1210mk2 compared to other high end TT?

The counter bore which houses the Ferite ring magnet is machined 'in situe' and contiguous with the machining of the location hole for the boss.
This ensures absolute concentricity of the magnet.
Also the bore is machined with a tollerance which address's the small changes in dimensions of the assembly and permits the accurate centering of the Magnet assembly into the bore.
The ETP PLatter is also run on my SL1200 test-bed for 2 hours prior to posting,
using a speed indicator strobe.
So you see there is no way the ferrite magnet assembly can be out of centre, however there will always be "experts" who
have never used an ETP Platter who are only to willing to give advice on what to do.
