Why does my system now have shrill top end.

Proposition: There are less Morphic fields 👻 👻 👻 floating around late at night. And early in the morning. Especially Sunday morning. Morphic fields are frequently misinterpreted as "power grid activity." You should notice excellent sound quality issuing forth from your system during those times, generally speaking. Very weather dependent, too, low pressure systems bad ⛈ , high pressure systems good 🌞. It’s doesn’t take a rocket scientist 🚀 to realize there are a great many variables involved, certainly not (repeat not) only one or two.

At the risk of repeating myself, this appears to be very much a circuit focused group. It seems my earlier post intimating the problem of the “shrill top end” could be *something else entirely,” something out of the blue, was taken down hard. You know, the suggestion that the culprit could be unrelated to the audio system entirely, I.e., not (rpt not) the amplifier, preamplifier, cables, power cord, room acoustics, or even the house AC. It doesn’t have to be the amp or the preamp. And I am not referring to any of the issues in Vogue such as fuses, wire directionality, polarity, out of phase conditions, things of that nature. But something a little bit scarier. I’ll be watching with some interest to see how this thread plays out. 😀

@uberwaltz  pardon me for saying so but now you’re the one doing it. Walk a mile in my shoes. 👣

I suspect the operative word is blowhard. 😡

Fascinating how the circuit focused group analyzes the problem as an amplifier issue and dismisses all other possibilities pretty much out of hand, and rather forcefully. A microcosm of how audiophiles tend to think?

Jea48 Huh? I wasn’t addressing anyone in particular. Thanks for the image anyway.

Tis probably best to think of snake oil as the lubricating liquid that makes the engine go. It also separates the MidFi from the High End, you know, just judging from the responses here. No offense if MidFi is your thing. Everyone has to be somewhere.

Having all the fuses and cables in the right direction helps a bunch with that sour and harsh sound. Harshness is one of the traits of incorrect direction. Too bad most power cord manufacturers don't subscribe to the idea of directionality. Oh, well, so it goes.

Next up, the absolute polarity thing. Or the Cable Directionality thing. Or the fuse directionality thing. Otherwise it looks like we’re back to them old Morphic fields back home. Waves of...information!

There are no standards for absolute polarity. - audiophile axiom

There are a lot of reasons why systems sound shrill. Especially as the volume is turned past moderate levels. But one reason that is not even on audiophiles’ radar is the dreaded Morphic fields. You know, the things behind Morphic Message Foils, the clever clock, and why telephone books are bad for the sound. After addressing all the usual suspects the distortion is still there! 😧 You see, folks, things are worse than anyone suspect. Much worse. Let the hand-wringing and denials begin.
