Sell a speaker you like but CANNOT optimize sound?

Has any one considered selling ( or actually sold) a speaker you own (or owned) and liked because you can't seem to optimize the "sound" to your tastes by changing electronics or cables,etc.etc.

PLEASE NOTE:..... I want to note that there are many reasons for selling a high-end speaker such as:... the living space changes, the speaker begins to annoy you and/or wife because of its size and appearance, financial or family considerations, or ....you reluctantly won't admit to yourself, you are just tired of the way it sounds, even after investing time and effort to optimize its sound
quality.

Should make for an interesting discussion!!!
