I contend that all these issues were accounted for in original system design. There are billions of CDs in use but only one Geoff - who you gonna believe?Actually, I keep an open mind with tweaks but I really think someone has to show a real problem to justify the tweaking rather than audiophiles tinkering with things for the sake of it and then claiming an improvement.
If we're going to go down the Roy Batty 'you won't believe the things I've heard' route we'll need a calibrated Geoff by submitting him to controlled listening tests.Regarding vibration I post the this link to Jurgen Reiss of MBL again (CD transport discussion starts at 3:40). As he is trying to sell very expensive equipment he takes the Fear-Uncertainty-Doubt approach to say how sensitive the CD transport is to external vibration. But, what he is actually saying is the CD pick-up mechanism works so well keeping the laser on track that you can use it as a vibration measurement system. As long as you keep any servo current modulation out of the audio path you are golden.
