@kosst.........the general public, like my sister, who enjoys music as much as myself, but she listens and enjoys music, through a Bose all in one table top system, and on her phone. The general public, I don’t think so. Just a handful here on the ’Gon think much of this as snake oil, you of course included. That was not the base of Art’s article, as he was talking to, and about, the " audio community ", not the general public, and that prices of equipment ( yes power cords and cables, too ), have gotten out of hand, and I concur ( btw, the general public does not read audio magazines ). Of my many audio buddies growing up, I was always the 1st one bringing home the expensive stuff, at that time. I was middle class, but found ways to purchase the equipment, and because I was in the business, I did get accommodation pricing from the manufacturers and rep firms, which always helped on new equipment, but mostly dabbled in the 2nd hand market. Maybe an upgraded power cord will enhance your system ? I know your F5 would appreciate it, how about you ? $ 30 from Hong Kong / China with free shipping for a 1 meter. Or a buy it / try it offer from the Cable Company ( many other sites as well ) Enjoy ! MrD.
