I spent 3 years in school studying to be an audio engineer, and have built all my own stereo set ups from random equipment and home made bits and bobs, but I am fussy about a clean signal and carefull speaker placement, do silly things like wash a record in the sink with soap and water, and since I run missmatched speakers, amps that are not built tough, die quickly, just occured to me to impidence match sides by daisy chaining random speakers till I get a match, liking that. But yep!, we are not whales, and cant hear at 200khz and dont need to hear the difference between mud and bananas, but I think a whale would.
