The noisefloor in this video sounds weird/different to most videos. I get a light sort of 'pressure' feeling in my ears with headphones on. But other than that it's really fine.<br><br>As for coil whine, it's usually an indicator of old and failing electronics to me these days, particularly cheap chinese made phone chargers without proper filtering have it. And that high pitched noise can also actuall back propagate onto the powerlines and interfere with the radio spectrum. As a HAM Radio operator I hate old CRT monitors and badly filtered circuits. ;)
