Dover, I agree with your aim of striving to retrieve all of the information as possible from the LP. There is no magic to the execution of sound retrieval from an LP: It is pure physics.
The effective coupling of an LP to a platter by use of a center weight or clamp and a periphery ring are very effective. I have found that the more massive the clamp the more stable the platform and greater resonance control.
I also found that increasing the mass of the center weight improved the sound extraction. Though, on initial use, I felt that the music had lost its vibrance. However, upon further listening, I discovered that there was greater definition to the music and less background noise. What became evident with the lighter-mass weight was that the resonance from the stylus was fed back through the audio chain. It was like hearing music played is a hall.
TTWeights makes a well-thought out center weight with a cupped underside to impart pressure on the LP to mate with the platter.
