What are your thoughts about the new Rega Nd7 Moving Magnet Cartridge?

I currently use Moving Coil technology myself. 

Latest purchase was a Lyra Delos at almost $2K.

There is always a debate over MM vs MC.  

Tracking weight seems a bit high at 1.75 grams. (hard on the music source??)

I wish they would use the Solid Boron Whisker in lieu of the bent, folded, aluminum cantilever.  I believe the Boron tracks better?

At $800 dollars it's not inexpensive, but I wonder if anyone has tried one yet?

Your thoughts??

Thanks!
