The "most foolish" loudspeaker tweak/upgrade ... is

You guys are somewhat restoring my faith in Audiogon!  Good to hear the silent majority (or maybe minority?) who have been beat down in the name of forum decorum whenever discussion of these "tweaks" come up.  Free or low cost "tweaks" is one thing, but the next step always leads to the high priced "audiophile" versions.  Yes, I haven't tried them.  No, I won't and don't feel bad or hypocritical about it either. 

Esprits4s. Thank you; spoken like a true renegade. Cheers to common sense 
and the ever healthy does of skepticism.

Long ago, I purchased a pair of speaker cables that dealer said were directional. He told me if I didn't like the sound initially, he said to reverse the connections. Go figure.......

My dealer told me the same thing.
At first they made the music too bright, so I reversed them.
But that made the music too dark.
So I reversed only one. Then it was just right.

They were Goldilocks cables but I don’t think they are available anymore. Bummer.

I think the problem is that peoples' mental self influence is often stronger than their audio memory or discrimination.  I feel it myself most times I try out a new piece of audio gear that I've just purchased with the intent to upgrade. 

Actually, the poster above's comparison to fashion might be the best I've heard.  Fashion is totally subjective and in no way quantitative.  Of course fashion is fi kle and influenced by celebrities, price, ....   There is no objective measurement nor any pretense of one...  The audiophile world is very different on that account.
