Hey! What's with the dumping on us Gen X-ers huh?
Saying anything will be gone after any particular generation is just plain arrogant. The world will go on without us until at least the Sun goes Nova and burns it up.
News flash. Every generation thinks theirs is the best when they get to the sunset years. It's called Nostalgia. One could always try and stay "hip". One could actually believe it but trust me that's not what the young 'uns see. They see Uncle trying just a bit too hard to be cool.
Now let's get to the specifics. High End? What is it anyway? It should be about quality but it has another component that is often neglected. That part is how it most closely fits with the individual consumer's wants. High End Audio is the niche in the audio industry that mirrors the niche in fashion that provides bespoke suits.
Let's face it. A LOT of what's spent generally goes to cosmetics. Sure so called purists say it should only be the sound that matters. I had a good hard laugh in another forum when a gentleman from Brazil retorted "Why, is your wife ugly? Looks don't matter? You have ugly wife?"
Everyone keeps harping that differences are oh so small. Fine. Let's assume that were true and bring in the wife analogy. Between two equally wonderful women, would you go for the pretty one or the homey one if you had the choice? I dunno about you guys but there ain't no way I'm going to be a hypocrite. My wife is beautiful and will remain so forever in my biased subjective eye.
It's not about generations. Every generation will have those that are willing to go the extra mile, it's only WHAT the extra mile is that changes.
