In order to increase the rotating mass the platters have to be couple much harder then my lightly-applied reel-to-real tape. When you stress platters horizontally harder it creates own problems that do have sonic outcomes. In addition, the only way to do flywheel is to use two belts (with a mechanism of vertical holding of the bridge belt); otherwise you apply an extra horizontal force to the motor, with many other negative consequences to the motor and the motor’s power supply.

I did not say that this flywheel is not effective. I say that I do not know as I can’t confirm it. I personally doubt the flywheel effective because considering the mass of my platters and the coupling force of my belt the platters really does not see each other. When people do couples the platters hard and then claim that it “made huge difference” I always ask them questions and always was able (so far) to find a lack of consistently and credulity in their judgments about the flywheel. I also I do not know how to isolate the sonic changes that inflicted to a platter by applying a horizontal force from the conic changes that reportedly might be due to the flywheel effect. If you take a small 100g rubber wheel with bearing, press it to a platter and let it to spin along with the platter then you tilt the platter’s “beating” and will change the order of the mechanical filter. This would also have the “sonic difference” primary at the very-very lower frequencies.  How to abstract from this change while we evaluate the flywheel effect I do not know. To subscribe to the people who clime: “my bass dramatically improved with flywheel” and who are playing the 50Hz ported mini-monitors is really insults my inelegance.

Once again, I do not know if the flywheel is affective as I never was able to conduct within my conditions the methodologically “clean” experiment. In addition, there are many others, the really auditable and the really important things that should be taken care in case of my “tandem”, and the flywheel considerations are really out of my radars.
