I grew up with homemade Hi-Fi and later Stereo bi-amped & tri-amped systems; can't stand to hear music played on any less than full range system. May be my musician training of my ears/brain. Built some nested boxes with sand filling in-between like Wharfdales, with Wharfdale drivers and horns made from battleship megaphone drivers (no kidding!) attached to custom planed wooden horns. In early 90s didn't like current new loudspeaker systems that didn't require a mortgage, didn't like most of those either, a local store had some JBL L100 I bought eight of them for peanuts, two stacks of four high powered by 4 Audiosource 80W RMS/ch (conservative), now I'm down to two stacks of two L100, the bottom pair used for bass only.
I love the warm high-energy sound of tube amplifiers, now I use solid state for clean power.
Louspeakers are the weakest link in the audio chain, with microphones weakest link at the other end; imho, quality of all the equipment in-between matters little, provided there's enough power for the loudspeaker system.
Audiophile addiction shares much with Photography addiction, similar draw, boys of any age (including females) like to play with their toys.
The physics are similar, acoustic & optics are wave phenomena.
