I'm a retired semiconductor engineer. I'm also keyboard, bass and guitar musician (order of competency) and have played professionally (classic rock, blues, originals) on and off. I also work on instruments (primarily repair and restoration of Hammond organs and Leslie tone cabinets) as well as stereo equipment. I have recording studio in my home (pro ATC active monitors). My older son, 24, is a professional EDM musician; headlining an outdoor festival this weekend in the forest just south of Flagstaff, AZ. My younger son is also an aspiring EDM musician. My wife enjoys playing our Steinway piano.
All of my professional musician friends think my stereo systems are silly. My sons, even they grew up around great stereo sound, have no desire to own anything that isn't relatively portable. I applaud them for their relatively non-materialistic lifestyle.
