i was wondering if anyone could offer any sound (!) advice on optimizing the way that devices are plugged into the AC lines. for instance, should care be taken to isolate components with traditional power transformers from those with switching power supplies, if one has access to different filter banks? does it matter if switching power supplies are isolated from each other, or does their means of operation already make them relatively immune to the noise generated by other switching power supplies? my guess would be that the switching power supplies would be more immune to line noise that traditional transformers, and that isolating the two types of supplies would be an important rule of thumb for powering equipment (and obviously as much further isolation from component to component as is feasible would be desirable too).
i would be very interested to hear thoughts on the matter.
