Acoustic Signature Thunder

Anybody using this turntable?

one, two or three motors?
one, two or three armboards?

Appreciate your comments on it... Thank you
Nobody has any experience on this?
I have a AS Final tool with platter upgrade and 2nd motor added and it sounds better. Detail and tones are more pure
I used to use the Mambo. The precursor to thunder . It was an amazing TT. I strongly recommend the thunder abs suggest one motor.
