I don't think all audiophiles are hell bent on spending the most possible on items that couldn't matter less, I guess we all have different definitions in mind as to what an "audiophile" really is... To me its someone that enjoys quality sound, I have heard $500 systems that sound awesome and I have also heard $18K systems that sound terrible, I don't think the definition has anything to do with cost of equipment, just that it is well thought out and setup...
Take me for example, my bedroom system consists of a Red Project turntable, a D1 dac, a 40w tube amplifier, and a pair of Tekton Lores {red}, {also some red speaker cables I made and a couple pairs of red headphones, for good measure...}.... While the system sounds very good {I love it with live music tracks} I could have easily put something together for much less than $3000 that sounds much better, but because it was going in the bedroom and I wanted something "classy" looking with a little attitude, I spent the extra and settled for less performance, but everyone that sees it is most impressed with its looks vs my other systems that sound much cleaner and more accurate... I do spend a good amount of time listening to it and do enjoy it for what it is...
So not everything has to be aimed towards the absolute "best" sound, enjoy the aesthetics and the attitude of the equipment, after all it is like furniture in our homes... I own 3 cars and 2 motorcycles that where made before my parents were born, not because they drive great, are great on gas, or super fast, its because they are nice to look at and I feel good when I drive/ride them...
The Audio hobby is for entertainment, if you are entertained by $500 speaker cables and magical filter boxes than so be it, I won't blame you for "driving up" costs, that would be silly, if a company wants to charge 10 times more because someone will pay it, than that is not your fault, its mine for considering paying it.. There will always be a company like emotiva that comes along and sells for a fair price. Blaming the consumer or distributor is not the rite thing to do, that is like blaming the guy that drives a $190K Benz for me not being able to afford one, not too responsible, is it?
Think about it this way, you buy what you can afford {if you are smart}, you buy the best sounding system in your budget by comparing and using your likes and dislikes to make the decision Sound, aesthetics, customer service, warranty, product history, availability all have an effect on your decision, so you factor them all in, conscious or not... You get the system bought, set up, and play your music, you are happy with it, happy about the speaker cables, happy about the sound, and how it looks on your tv stand. You enjoy it when ever you play it but you are always looking for the next upgrade... You are an audiophile, whether your budget was a dollar or a million dollars, no where in the definition does it say anything about money... Just enjoy the system and the sound, I wouldn't want the guy with $500 cables judging my home made cables, so I won't judge his....
