Robert H. Levi over at Positive Feedback is quite enamored with the MAG-LEV.

His are the most through reviews I am aware of, three installments thus far, latest here
https://positive-feedback.com/reviews/hardware-reviews/mag-lev-ml1-turntable-part-3/.
He details the limits within which it must be used. Chief among those are it must be precisely level and tracking weight must be in range of 1.2 to 1.75 grams.
Within those limits and with some tweaks he reports:
"Combined with the E.A.R. 324 phono stage which allows for MM tweaking, the finest interconnects and power cords, it is outclassed only by my Grado Epoch/ EAT Forte S combination in my system, $20,500 retail vs. $4400 including my custom changes for the ML1. Note, the ML1 is just as quiet and dynamic as my top reference. The big difference is the extraordinary Grado Epoch cartridge is noticeably more detailed overall at 13x the cost of the Ortofon."
