"We tend not to think too much about the power that we use for daily activities, and this includes sound systems. I doubt that anyone would be heard to complain that their morning coffee tasted odd because of mains interference or distortion, but there is an entire industry that will try to convince you that without their mains filter, sinewave reconstruction power supply, isolation transformer and/or $5,000 power cables your audio and video systems must be horrible (and your coffee will taste like cat pee as well!).
Mains distortion is commonly cited as something that will cause the soundstage to be contracted/ compacted/ eliminated, and that the distortion will cause a loss of clarity, soften dynamics and mangle the bass 'slam' from your subwoofer. Naturally, we can expect that micro-dynamics will be damaged beyond repair, and the 'air' between instruments will be cloudy and grey with a 35.7% chance of reproductional ineptitude. "
LOLOL, I like this guy
