Does residential radio-frequency interference cause audible problems for a turntable setup, especially with a WiFi router or mobile phone a few meters away? The cartridge and tonearm would be places that are affected if there is any issue, especially with a sensitive moving coil cartridge. Would it make sense to use aluminum foil on top of the whole dust cover?
For turntable noise, it has been considered elsewhere that WiFi and cell phones can be a significant problem:
"Noise can be injected either via magnetic induction or from electric fields. And not just into the phonostage; noise can be coupled into cables, tonearm, or the cartridge itself.
"Try to isolate the phonostage. Remove all WiFi routers, tablet, laptops, and cell phones that were nearby."
"Position the turntable at least a few feet away from electronic devices - especially high power electronics and devices with wireless transmitters. TVs, routers, cordless phones, and even light dimmers are common culprits."
So how paranoid do you think one should be about this, and specifically how relevant it is to equip a turntable with a kind of suspecting tinfoil hat in the form of aluminum foil shielding that covers the transparent lid?
