Tweaks that didn't work

DSkipDSkip Posts: 13,519
I thought this might be fun. We always try to ink out the most from our systems but sometimes it doesn't work. What are some things you guys have done that simply did not deliver?

For me, it was upgrading the power cord on my Shuguang monoblocks. I heard improvements on the pre but not on the monos. Not sure why it was, but I opted to keep stock power cords on those and spend money elsewhere. I've heard improvements on every other component since. Just a weird anomaly I guess.

    Heh, I used that on my mass-loaded TQWTs. It worked OK... but the Moretite's forever stained (for lack of a better word) the unfinished front baffles of the loudspeakers :/

    Cable elevators, I would suspect. I could see their use on carpeted floors to reduce possible static electricity, but on tile or wood floors...meh. I use them now because I already have them, and they make me look cool.

    Good friend said I should try toeing my speakers in...yeah...the ones you DON'T toe in...told him repeatedly it'll be bad. So he does it and the soundstage collapsed so badly. Out comes a CD case to align them back to the wall again.

    Yeah -- but I remember it from the 1990s.
    I still have a CD-R I burned of Patty Larkin which I green-penned. I labeled the disc "Green Pen Patty" -- with a green Sharpie*, of course.

    * Not a green Shar-Pei. That'd've been weird.

    I use to have one of those black disc you placed on top of the CD disc you were gonna play, which was suppose to creat some sort of magic. Problem was, you needed a cd drawer that was fairly deep for it to work. This was like mid-late 80's. I think it was suppose to "help" the laser by providing a dark background to the disc. I would imagine it's already pretty dark in the player, once the drawer is closed.

    Like the "free energy" devices on the internet, there's a shred of semi-reasonableness to most of even the wackiest "tweaks" to make a semi-rational person think, "yeah, that could work -- let's get one and try it!" :/

    Another tweak I tried that didn't work was the little Ferrite-composite disks from a certain company offering free trial units a few years back. I remember several on the forum joining in as well. For me, it was a very negative effect. I still have them somewhere.

    Using too many tube dampers on the tubes in a piece of audio equipment. May work to reduce microphonics on a defective tube, but the real solution is to get a better tube! Especially with signal tubes, overdamping makes the sound output flat.

    Interesting -- I tried 'em too (independently of you all) and felt as though, if they did anything, it was positive, so they're still ensconced. Heck, I even changed speaker cable & moved them to the new cables.

    (-- and, no, like most wacky hifi tweaks, there's no reasonable reason to expect 'em to do anything, good or bad... but, then again, they were free to try; the bar was pretty low!)

    You know, I can't think of any. For me tweaks have a cumulative effect and I haven't been one to do one at a time. I usually will do a few or more at a time. I also haven't done a lot of tweaks recently so my memory of what didn't (doesn't work) is a bit foggy.

    I am also one to try tried and true tweaks and don't experiment too much so all of the tweaks I can think of have been pretty successful, or at the least not detrimental.

    Probably should define tweaks also. I have tweaked many things by upgrading parts. Not sure if that is the "true" definition of a "tweak".

    Good topic

    I would consider any minor parts swaps as being a tweak also. For example, replacing the cheap stock fuse in a piece of high end gear is supposed to have some benefits. I have not tried that myself, but I haven't seen someone who did it be disappointed.

    I would consider modifying the crossovers in a speaker to be a minor to major upgrade rather than a tweak.

    Black socks have a better mids control without shaving off the highs. YMMV of course.

    This is a good topic -- but I see it heading south!

    Like @heiney9, I have tried mostly, if not only, tried-and-true tweaks and mods that others have suggested on this Forum. And, I have a bad habit of doing more than one thing at a time, which makes isolating success and failure of any one "tweak" difficult.

    I'll keep thinking about it.
