Isolation Cones/Bearings placement on CD Transport

In general, place two on the heavier end and one on the lighter weighted end. Removing existing feet should help. Various placements should also make a difference therefore you need to experiment to see what sounds the best to you.

In no way do I mean this to be a flippant reply, but you should just try both arrangements and determine for yourself which you prefer. Your ears with your equipment beats anyone writing and telling you what to do.

There are no exact measurements in placing cones or bearings under a component. Many manufactures do suggest an initial placement, and the rest is up to your listening skills. I have found that a slight movement in placement of a cone can change the soundstage and imaging.

I'm not sure about isolation bearings, but with spikes/cones/points, the ideal location is to place the 'vibration control object' dirlectly underneath the spindle, and also directly underneath the power supply. And for amps and preamps, the ideal location is always under the power supplies whenever possible.

I believe that weight distribution of the chassis does not really matter as much except in the case of safety where the component can more easily lose it's balance.
