Tweaks That Don't Work


This may be the subject of some discord, but a great community service would be to help others not waste money on snake oil.

Please let us know what you've tried that had no impact - or negative impact, even - on your system. Also, if there are tweaks or products that are only useful on some systems for whatever reason, please let us know what kinds of systems do and don't benefit from the particular products.

Some of you out there have tremendous experience trying to squeeze every last ounce of performance out of your equipment and probably have a laundry list for us - let's hear it!

Aggielaw, I see this as a very rational request and wish that it could be implemented without rancor, but I just don't see how. My latest successfully implemented tweak will always be someone else's snake oil. And I'll likely think you lack perspective or hearing when you tell me that using XXX made a vast difference in your system. I think its enuf to "discuss" the efficacy of each tweak as it comes up and let subsequent subsequent interests in the tweak by satisfied either thru renewal of the thread or thru forum research. This way there can be a more complete airing of opinion, not just a consensus listing, or a listing with allowance for a summary w/proviosion for the numbers of folks who agree or disagree.

And, most importantly, it will give us something to argue about ad infinitum, ad naseum. :-)
Newbee, I had the same thought as you. Ironic that I tried to re-edit with why I did not think they worked, but you posted after me!
Good spikes on floorstanding speakers do work if the mass of the speaker is great enough to keep them firmly planted(unless your floors are creaky and resonant).
Throw rugs and plush furniture do work to calm a lively room.
Good (not necessarily expensive) power conditioners on things that spin work.
The cost of most tweaks far outweighs the benifit though. Even the tweaks that do work only improve the sound relative to the capabilities of the equipment. Careful placement of speakers can make a modest system sound quite impressive and enjoyable though.
One problem will be that if someone discounts any tweak, no matter how ridiculous, 3 others will jump up to proclaim it the holy grail of audio. Say something bad about green pens, magic rocks, Intelligent Chips.... somebody will be get upset and offer that your ears or your system are clearly not "resolving" enough.
