computer isolation

my mac mini and nas both are on vibrapod footers and resting on a thick maple butcher block....it can't hurt

I'll go out on a limb and say no. If you're output is a digital signal then no for sure and if your outputing an analog signal then I doubt there is any level of isolation that could improve the signal.

Unlikely unless your laptop has tubes or uses a stylus to read a vinyl groove. Modern electronics is not micro-phonic. Frankly, if it was a problem then passive speakers would not work as the crossover would pick up vibration.

Just another urban legend.
