I glean from both responses by individuals connected with this equipment and it's testing that none of the results are "official". Therefore, no actual hard data will be forthcoming. Looks like the standard audiophool playbook is being followed, what a surprise! Signals in the microvolt range are hardly rare and in the business of precision electrical measurement and the equipment employed, 0.01V is a fairly stout level. Signals in this range can be measured accurately by professional equipment in the noisiest of electrical environments provided adequate precautions are taken. Furthermore, if there is the possibility of a critical measurement being influenced by random EMI, those measurements should be made in an appropriately shielded room (Faraday cage).
As far as medical equipment is concerned, EMI is taken seriously as it can undoubtedly affect medical equipment. From a brief amount of research, it would appear that the bulk of the threat comes from emissive EMI rather than conducted EMI. Unsurprisingly, the main culprit is the mobile phone and unless I miss my guess, it was the advent of the GSM system and the ugly sawtooth it used to transmit that made a ban on mobile phones near patient monitoring equipment necessary. Happily, GSM has gone the way of the covered wagon.
What surprises me is that outfits like Shunyata seem to think that their snake oil tactics are immune to scrutiny and require no verifiable proof. I figure they are filled with confidence after fooling many hundreds if not thousands of people who accept the voodoo claims connected to their audio products. New member kemoraud, would you care to share some pictures of your lab and maybe some before and after measurements?
