Re the Kenwood L07D and the Technics SP10mk3.
In understanding the design we must remember these turntables were built for quite different purposes or use. The L07D was an all out assault to produce a state of the art tt for home use. The SP10mk3 was designed primarily for broadcast and archival use. Consequently the L07D has one of the most sophisticated plinths of any tt manufactured in terms of rigidity, energy dissipation and ease of adjustability for accurate set up. The SP10mk3 has incredible torque, very fast start up and stop times and a crap plinth.
We dont know what was in the minds of the Technics designers - the choice of the mk3 motor may have been more to do with the fact that it was the motor used in cutting lathes and readily available at the time. What is interesting is that when they increased the torque they also increased the weight of the platter significantly from the SP10mk2.
