One can be an audiophile as well as a music lover, of course, BUT "Music Lover" should not be any category of audiophile. I've know a good many genuine music lovers who were content with extremely modest systems.I would propose a fifth category - The Music Lover. Their most important outcome is to hear the music as it was recorded and will use a combination of measurements, listening and others opinion (often in that order) to guide their journey.
The biggest challenge we face as humans interacting on a forum is the fact that we are not designed for this type of interaction. 70% to 90% of communication is non-verbal so that leaves a very wide margin for error. I do however strongly agree with the spirit of the sentiment.
Many undoubted music lovers have, e.g., "compact stereos". To be sure some of these are pretty decent but they aren't going to match any well-thought out system worth a few thousand bucks. Further, that sort of music lover has little if any interest in room treatments or critically placed listening position, not to mention cables or similar distractions. Yet they are certainly music lovers and love listening.
