From things I've read previously even the PEM's can create and/or aggravate white noise and hiss. Given that I think it entirely possible all current Experts may well have the entirely wrong PEM for wi-fi reception since they were likely purchased/installed before Air was considered and they're likely still installing old inventory on current assemblies. Sadly there are PEMs available that are specifically designed to remedy and/or diminish white noise while still carrying out the features Devialet wants to filter or provide protection against. Things like this can be a huge problem in over-exercising freebie upgrades when implemented gear didn't include going a different direction. I'm still interested, just for grins to see how Air might sound on my 200 post-reassembly tho I'll be terribly disappointed if that's the only place I notice an SQ-enhancement. The more I ponder this tweak the more hopeful I become but have to limit myself in soothsaying pre-natal chicken birth rates.
