Tweaks you got rid of because they were not effective (enough)?


There are some audiophiles for whom cost is no object; they buy what they wish and every single tweak and gadget which promises to improve the sound. And the industry is all too happy to produce such tweaks -- often made of expensive materials with elaborate engineering explanations. Those who question the value of these tweaks are frequently accused of being "naysayers" who are either too ignorant or insensate to realize that "everything matters."

Of course, money spent one place cannot be spent elsewhere; expenditures on tweaks take the place of other more central factors affecting the sound. In some cases, those tweaks are worth it; you can hear the difference, and that $400 (or whatever) really could not have improved your speakers or sub or amp, etc.

So, the question here is simple: Which tweak have you tried which, after some experience and reflection, you realized was either *not* effective or not the most effective way to improve your system?

Vibrapods.  They seem to make the sound worse, not better, and leave a nasty residue.
@tbakin It’s always good to have a reality check with one’s self about whether one hears a difference or not. I’m glad you enjoyed the question I posed; there are so many debates over these products and phenomena that I wanted to try just to elicit a list from people of what they decided, for themselves, were just not helping. It’s likely that none of the answers here can add up to anything like an objective answer, given the range of different equipment, rooms, ears, and tastes involved. But some patterns will probably emerge, patterns which may provide at least a pretext for some of us to try something, avoid something, or do some interesting experiments for ourselves.

Good post!    I have tried and owned many of the “best” Cables on the market, done blind tests with friends.   Seriously, if we’re all being honest.  I have friends that have some of the best stuff on the planet, and they literally picked the 100 dollar cables, power cords, etc.  at least 50% of the time.   Even if the stuff specs out better on measuring equipment, you just really can’t tell the difference!.   15,000 for a pair of cables?   Come on man!
