Thanks Graham.  They sound nice.

Thanks Graham.  Fair comment although there is a difference between transmission of a signal to 'work' and transmit as much of a pure and accurate signal as needed in a first class analogue (or digital) system.  Whilst I am certainly not saying there will be a detrimental effect, my experiments with differing substances under my amp and CD player (incl, wood, metal, rubber, felt feet or supports) does provide subtle changes to sound and presentation -similar on both.  Some ridiculously expensive speakers are active so sure manufacturers will have tried this and speaker crossovers also are mounted even closer to the drivers.

I'd forgot that one. Thanks for the link.

My guess is that all the worry about vibration affecting electronics is a hangover from the valve days. The gain devices in a solid state amp are silicon chips solidly mounted inside plastic mouldings to the extent that they cannot vibrate independently. My thoughts are that if vibration in sensitive solid-state electronics were a real problem, the aviation industry would have discovered it? I'll have to check.
