Generally, people who spend $180K on speakers do not care about resale value; they only want what they want (nothing wrong with that). Trade your speaker in and buy another pair with the custom paint job and be done with it. You probably don't make your living from audio sales, therefore, why not leave it up to professionals and just get what you want? As for a custom paint job, not a bad route if you have the time to invest in the research, plus the hassle of getting it done. Just trade them in and buy new ones.
Focal Grande Utopia III EM's
I am thinking about selling my black Grande Utopia III EM's to option a custom color. I am wondering what the market price would be since I am pretty sure that I am the first one to be considering the sale. Please email me with feedback as well as responses to the sale idea.
