Hi, I've decided I'd like to try a 401 bearing on my 301 deck but I have to raise the platter slightly to be able to achiebe this. I see this as an oppotunity to reduce the vibration of the bearing going into the 301's chassis. I have two questions :-

1. Is it better to reduce vibration over a larger or smaller surface area i.e. would 3 simple rubber "nuts" be the best solution or would I need to make a base plate that covers the entire surface area of the bearings underside/

2. Is it better to try and reduce a vibration's frequency into a specific Hz that is not audible or poses a risk in creating spurious resonances that can be picked up further down the line like in the chassis, platter, tonearm?

Hope these make sense.
