There area number of definitions of audiophile. My favorite is: someone who’s audio system cost more than their car. I have qualified in that case since the 1970’s… typically 2x or more. It isn’t a term about exact sound quality, it is about commitment to the pursuit… definitely in the fanatic category… in pursuit of the absolute sound.
My partner of over 35 years jokes about there being normal dollars and “audio dollars”. One hundred dollars equals one audio dollars. I will not pay a couple hundred dollars for a new lamp… but $5,000 for new interconnects… no problem… a bargain.
