Hi,

So it does. I work also at a Hospital.

However the mains cable on my monitor is shielded and has a ferrite on it and our server room had just had £ 15K worth of APC ON LINE UPS (think of it as an industrial and acoustically very noisy version of the PS Audio Power plant or the Audiophile AMS we distribute) installed to power the whole floors computers (not just the server) as the crappy local mains caused standard UPS's to have flat batteries within a few month (they where constantly boosting/bucking) and as many PC's where dying premature heat death plus many dead powersupplies (a lot of really important gear - that is medically important has had such protection for ages BTW)...

But I'm sure this is all just bunk anyway and past that no doubt non of this extreme mains variability (215 - 260V over 24Hour period, THD up to 15% and wide ranging frequency variation)  would ever be audible in commercial grade audio gear of elevated quality and most certainly not when applying a double deaf test and as we all well know, the Noble Flying Pig is heraldic animal of our IT Department, to illustrate the great performance and reliability of their network and servers.

Guys, your degree of reality denial and concious deliberate reality alteration surprises even a hardened cynic like me.

Ciao T
