What amazes me are the audiophiles (e.g.on audiogon) who use every tweak in the book, upgraded power cable, cable risers, new AC outlets, power conditioner, audiophile fuses in their amps, footers under their components and on and on. And with every tweak there is a reported lowering of noise floor and removing of a veil. It's as if audiophiles systems have a virtually unlimited dynamic range and audiophiles have hearing with no limits, able to hear "lowering noise floors" into infinity. I have a feeling some of these audiophiles will have improved their acuity to such a degree they'll become bothered by the background radiation from the Big Bang. Luckily, there'll be a product to help with that
