that there is an improvement, I do not doubt it but, the problem would be to change the disc with the plate in motion.
However, I had Hommage 23, taller and heavier, but when I found that it was slightly eccentric, I opted for the original foam, because the eccentricity of the Hommage, given the weight, could affect the performance of the rotation.
In my opinion, Mr. Firebaugh designed the Amadeus in the smallest details and it is better to stick to the original accessories, such as the transmission belt that he chose to minimize vibrations. Needless to put nylon, carbon, dental wire. The polyester thread, if stretched like a guitar string ... doesn't sound!
