Are these PC's being strapped to the side of a launcher or something?

Here comes the brass neck.

I want to hear some brass instruments through this set up. Would be awesome I'd say.

Maybe we should all fit brass dampeners to our heads to stop all that excess vibration... lol

I'm sorry but I cant hold back..... this is absolute nonsense.

how can you be so sure ? it's a heavy mass non ferrous metal, so will have an electrical and physical damping effect. Not something I'm about to try, but if people hear an effect then all good.

It is nonsense. What level of vibration are we talking about here???........its in a living room for f*ck sake.

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.

It astounds me that a thread on phono cartridges, something that makes a real difference, gets barely a few replies but a topic like this here will be a 20 page clusterf*ck in no time.

As you weren't listening to the effects of vibration on music your anecdote isn't valid. It astounds me that someone with such a claim on scientific knowledge isn't more open minded. Is it really necessary to imply those that dabble in these things are idiots.

This is where the entire arse falls out of your argument. Ears are EASILY fooled.

Never called anyone an idiot btw. I was just attacking the concept of 'electrically damping' a processor in a domestic environment and why I think its nonsense.

I have to disagree here.

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.

To give you a quote:

The sound critical electronics of the NAC 552 are mounted on a brass sub-chassis which is fully suspended on coil springs at a frequency below the threshold of human hearing. This method of suspension maximises isolation, hence minimizing the effect of vibration on the highly sensitive electronic components
