The price of a component only matters if one cannot afford it. The problem of discussing 'expensive' equipment as a 'luxury or boutique item only occurs when it is out of reach of ones' wallet.
Being 'relatively' middle ground (my stuff is now in the $5 grand major stuff, $2 grand minor stuff each range) I can appreciate the person with modest investments in a system who , just like the wealthy, wants to maximize the quality of sound he/she can afford, And, can also see why folks with expensive systems can and do spend hundreds of thousands to find that SAME goal of musicality in a system they can afford.
We all want a nice system that can actually play music. Better to agree on that as a first principle. Than to argue whether expensive stuff has a 'value'.
=============================================
Added: then the idea if esoteric: Having unusual or obscure equipment is a personal thing. i tend to want mainstream products, from companies that have a long and proven track record because i value the safety that represents.
However I DO appreciate the unusual, and exotic. Being lower middle class monitarily i feel I cannot 'afford' to indulge my whimsy. I wish I could be braver!
Since the desire for the exotic or unusual is a personal idiosincratic one, I guess it does NOT depend as much on one bank account. (though, it certainly could help to have more money available)
many audiophile LIKE having an unusual product they 'discovered'. This used to be more important BEFORE the internet levelled the playing field for new and unusual equipment. Now, as soon as YOU discover a new, exciting chunk of equipment, so does EVERYONE else!
