One thing I've learned in my DC motor travails is that there is a correct torque for a given platter mass.
When I experimented with higher torque motors - everyone in the multiple evaluation sessions I conducted agreed with me that the sound took on a harsh edge.
From this (and other experiments) I concluded - puny, but not too puny.
Now, as I've written both on this forum as well as my Motor FAQs page, every element in the moving system is a variable (belt, platter, bearing, lube, motor specs, etc.). Change any one of them and you need to start over with your evaluations.
AC motors are completely different kettle of fish, although I'm comfortable in asserting that there is a correct torque specification that will balance in a musically coherent manner ... IOW, you can have too much as well as too little torque.
There's quite a bit involved in optimizing these power to mass relationships, and like everything else in audio, the numbers are but a departure point.
We're a finicky lot, and our hearing has evolved over tens of thousands of years in a sophisticated manner which we're just beginning to learn how to measure.
