Wow, never thought anyone had much interest in audio on this blog... But, then again, TUGGERS are always full of surprises.
I have been into audio since my college days (early to mid 80's) and still listen to music and movies through them. I agree it is a fast fading hobby and also that for many years the emphasis has been on how loud and how convenient audio can be. Many examples of terrible sounding equipment that sells because of its name, clever marketing or because it is wireless or compact. Certainly not all wireless or compact speakers and gear fits that description, but, to my ears, most seem to.
Klipsch speakers are great for their efficiency and therefore do not need gobs of power to get very loud. As far as selling the Klipsch speakers, I would look at the Audiogon website (
https://www.audiogon.com/), as that is where you can ask questions, read the blogs, and even get an appraisal for most mid to high end audio. Your speakers may not sell as fast as on ebay, but you will more than likely get more money for them.
I have always liked the Maggies! I too have put an emphasis on imaging, accuracy, and full range sound reproduction. Personally, I use the Vandersteen Quatros and surrounds but would not be unhappy with planar speakers.
