"Where Alternating Current (AC) is concerned, we’re relying on a century-old technology created for incandescent lights and electric motors—technology that was certainly never meant to power the sophisticated analog and digital circuits used in today’s premium audio/video systems. To properly accommodate the promise of today’s ever-increasing bandwidth and dynamic range, we must achieve extraordinarily low noise across a very wide range of frequencies.
""Further, today’s power amplifiers are being taxed for instantaneous peak-current demand, even when they’re driven at modest volumes. Although we have seen a substantial increase in dynamics from much of our audio software, the loudspeakers we employ to reproduce them are often no more efficient than they were two to four decades ago. This places great demands on an amplifier’s power supply, as well as the source AC power supplying it.
"Our systems’ sensitive components need better alternating current . . ."
~ Audioquest's pitch for its new $8,000 "power conditioner." (https://www.needledoctor.com/Audioquest-Niagara-7000-Power-Conditioner)
Not a typo. Not $800. Eight kilobucks. I could build a hydro-electric dam on the creek running through our place for less than that, if FERC would let me. Makes a $75 Chinese-built Variac from Circuit Specialists look downright niggardly.
I dug up the Audioquest BS on my own, but there's a new Facebook chat group I think everyone here might enjoy reading and posting to. It's San Francisco-based Audio Bull$hit. AB's (not to be confused with A-B, Holger) mission statement reads thusly:
"Discuss the bull$hit that is High End Audio and other random musings (audio reviews and products you believe are story telling bullshit, psycho-acoustics, placebo effect, jokes, bad album covers, vintage ads, music news, equipment, setups, what you are listening to, Q&A). Maybe even learn something along the way all while having fun!") There are no required entry creds. They even let me join. Enjoy!
