Yes more motors are better in my experience. There are two camps here. Camp one: use a single low torque motor coupled to a very high mass platter. Camp 2: 2 or more high torque motors turing a low mass platter. I have been in both camps in the past, and I can honestly say that multiple motors turning a low mass (relatively) platter produce a much more involving more soulful, more punchy presentation that is at the top of the PRAT scale.
Yes more motors make more noise. Yes coupling 2 or 3 of them to a lightweight platter provides more opportunities for hum and vibration to reach the platter. Thats why the platter is low mass. Its like a bell. A large diameter bell transmits more collected energy into sound pressure waves than a smaller diameter bell. Thick massive platters tend to just collect, store and transmit more room energy into the stylus than with a low mass platter. Low mass platters don't collect or store nearly as much energy. There is less platter to do so.
I know common sense would tell you that a more massive platter will isolate the record and stylus from freewave airborne energy more effectively than a low mass one, but this assumption is incorrect.
That low mass platter being driven with high high torque is what produces some of the most involving analog I have ever heard anywhere.
I am not a physicist so I can't give you the numbers. What I can say is that hearing is believing to me. Oh yeah.....there was a question here. More motors is better!
