All the top models of Naim power and pre-amps, CD-players and streamer models have mass loaded and spring dampened constructions for their PCB's and I can asure you they have done more R&D into this than you have.

Pointless additions made to electronics by a hifi company. Now there is a surprise. It's only purpose is marketing bollox.

I have more faith in the skills of Naim R&D then in your remarks.
Naim is not known for poppycock products or marketing hypes

Fair enough, I couldnt really give a shit to be honest. Every hifi company out there has some spiel around vibration damping.
As for the 'lack of knowledge' on my side, I've been working on designs for the European Space Agency for a few years now, stuff that ends up in satellites and other systems with critical systems on board.

That's nice for you, but they don't make much music do they, these satellites?

All experience is worth so much as the context in which it was experienced.

My first experiment with isolation was a few half squash balls under a heavy power amp and and it did make a noticeable difference. I still pay as much attention to isolation under amps or power supplies as I do to CD players or turntables. I know it doesn't make sense but to my ears it makes a difference.

Speakers, TT's and some valves can be affected by external vibrations to different degrees but not electronics.

I've participated in plenty of vibration tests on electronics. The PCB, testboard etc is bolted onto a table. The table vibrates in the x, y, z axis so much so that the board is all but a blur to your eyes. Sometimes the board is subject to 10g acceleration. During each test the electronics are operating as normal. These particular electronics drive and control incredibly sensitive lasers so vibration affects would show.
The only issues here are mechanical or poor solder joints that can affected in the extreme tests.
