Out of curiosity I took a quick look at Robert Harley's well-known book "The Complete Guide to High-End Audio" to see what his guidance was on tweaks. He discusses them in Chapter 15 (out of 16). He indicates that these items can be used to address an "audiophiles' need to squeeze out those last bits of musical performance out of their systems." He also says that you should not even think about these items before making sure you have optimized speaker positioning and room acoustics first and having first built a solid foundation.
A few quotes I found interesting, while he did acknowledge that some accessories can certainly make improvements:
It seems that Harley's priorities align well with mine and many others that have posted in this thread. It's interesting that the Editor-in-Chief of The Absolute Sound used the term "snake oil". I honestly didn't expect that.

Other accessories can not only fail to improve the sound, but can actually degrade it. To make matters even more complicated, many accessories are completely worthless - nothing more than snake oil sold by less-than-honest promoters that have no effect on sound.
