I actually don't agree that Audiophiles don't give thought to the value (read, price) of equipment. They are very much aware of the value/price. Some either don't care, or the price is acceptable to them, or like me, they lose their @##?? mind on occasion and wake up the next day lying next to new "upgraded" equipment.
The OP is actually correct that some determine that different is somehow better. Until after acquiring the new unit, they listened for a good while and realize that in actuality, the replaced piece was better.
Some don't even know how to listen or what to listen for in order to determine "better". Some determine that changes in volume is "better" because they didn't match levels before doing their A/B comparison test.
It is journey for each and every one of us. We live, we learn (hopefully) and try to enjoy this hobbie and the positive interactions with others in this difficult, confusing, fun, stupidly expensive and enjoyable hobbie.
