David,
Wow !! Thanks for such a comprehensive reply. I think I "get it" a little better now. Very good point about the Relaxa shelf tilting. I had thought about the component weight causing the shelf to hover lower over the magnets but hadn't even thought about off balance tilting. It seems so obvious when pointed out ... of course this would remove the level surface required by the Aurios. I guess a half inflated inner tube is going to have the same problem.

It sounds like there is no cheap and easy way to provide both horizontal and vertical isolation. The reason I was especially trying to isolate my CDP, is that everyone seems to agree that the source is most prone to vibration induced distortion (along with some tube pre-amps). I will have space between my speakers to have each component on its own separate platform rather than a taller rack which may degrade imaging and enable cross-vibration between components. I guess Aurios underneath and mass loading atop each component will largely prevent the latter but will not prevent the imaging degradation. Also, I can't mass load my amp (Plinius SA100/3) which runs super hot or pre-amp (BAT VK-30) which has ventilation slots over the whole surface area of the top of the chassis.

Maybe I should put the amp on Aurios on a maple slab on spikes (or cones) on small maple blocks (or coins) to protect the tile floor. This would allow free space above the amp for heat dissipation.

Then build a rigid half-height rack for the CDP and pre-amp, with maple frame and shelves, spiked feet on small maple blocks or coins, and Aurios under each component. Possibly, sitting sandbags or lead shot bags on the bottom shelf would damp some of the vibrations on their way up to the components on the higher shelves.

Does this sound like the best value-for-money scenario ?

Thanks again,
Darren.
