The mind is a powerful thing, yes some things can be "imagined" however we shouldn't discount what others say; It's harder to explain when it comes to audio, as not everyone hears on the same frequency spectrums, so what you hear, is not what someone else can hear, it' varies from person to person and thus some audio systems, sound better to some, while sounding worse or the same to others.
There are extremely expensive speaker systems, that hurt my ears, I still use my Nakamichi Soundspace 11 from ages ago, because it has a neutral to warm sounding audio with rich bass, where many modern speaker systems and headphones hurt my ears, they can go loud, but they hurt my listening experience.
You think? The mind is a powerful thing indeed. How do you know the difference between perceived and imagined? Why can't we ever
measure it? Its really not hard to explain at all: different sound systems have different sound. And that's all it is. Different. Our attribution of a certain quality is 99% bullshit beyond a certain point, which has been reached convincingly way before reaching audiophile gear.
If you've used drugs while listening to music you know this in a different way. I could have sworn I heard more than just music on some festivals. New frequencies, too, that impacted me in ways I never knew before. And it didn't happen because my body was suddenly capable of something new. It happened because my state of mind was attuned to it. If you want something to exist, or if you seek that something, you will find it. Here's a nice experiment, try a shot from a helium balloon and lie down in between two speakers playing music. Fun times, you'll experience music like never before for as little as 0,20ct.
Its nothing different from religious people finding what they seek in religious places. The mind conjures it.
Similar things occur at extremely high refresh rates in gaming. There is a limit to perception, and that's where imagination starts to take over. Being more 'sensitive' is really not an advantage, it just costs you more money, and you can rest assured you're not enjoying music or gaming more than anyone else. Enjoyment is a mind state. Not a qualitative thing.
What's far more factual is stating that the music industry like every other will do whatever it can to make money. Everything else follows that. You actually said this yourself: 'what does sound mean to you' - that additional meaning of sound, for you, gets converted into spending ungodly amounts of cash on it to get 'some bigger benefit' out of that sound. But I can imagine there are millions on the planet for whom sound (more precisely 'music', and often quite specific music pieces too, its not about their sound quality but the
music itself) is an integral part of their lives, while they never even hear a good sound system. Do they enjoy sound less than you? I doubt that. That said there is of course a quality difference in audio gear. But like high refresh, at some point it just doesn't matter, and even before that, our mind is perfectly capable of filling in any 'blanks'.
The bottom line is, no matter how you twist it in your own mind, that you have money to burn and you burn it on this. That's fine. But that's all it is.
I am relatively new to the hobby, as I just ordered a pair of Hifiman Arya Stealth for 500 euro, 160 euro FiiO K7 and a FiiO LL-RC 2024 Balanced cable for the headphones (75 euro) and I am yet to receive them. I feel that I've spent a little more than what's reasonable. And yet there are people buying "Music Servers" for 30k like those? I feel there is a paradox in the audiophile community - the people, who are able to afford the absolute top tier equipment are already in their late 30s - early 40s and their hearing has diminished to the point of being unable to hear sound above 15 KHz, hence this kind of equipment is merely a waste of money. Meanwhile, the young people tend to be broke, despite being able to hear up to 17-19 KHz with ease. When I was studying in the uni (19-years old at the time), I was able to hear around 18.5 KHz, but due to a lack of funds my best headphones was a pair of Chinese IEMs for 25 bucks. Now I can afford better headphones, but my hearing is down to 16.5-16.7 KHz. and I am only 25-years old. By the time I am 40, I'll probably hear only up to 14 KHz. So it will make little sense for me to buy a 30k euro equipment, even if I could easily afford it.
The best case seems to be to buy a decent mid end pair of headphones, while you are young and enjoy your time with them. Because all of the money in the world can't buy back your youth and hearing. Those types of spendings seem to be a part of the mid-life crisis at least in my opinion.
See this is a whole other category of audio than what's in the topic. Sure, you can spend a few thousand, or even five thousand, on great audio gear and that will certainly pay off. But if you have to start stretching to ten and keep buying? You might want to start reflecting. If you do audio with common sense, you buy stuff once, and you stick with it for a long time - 10+ years at least, or double that, easily, if you buy quality gear. It actually
pays off like that simply because its built well and does the job well. If you do more than that, you're practically just in it for buying stuff, not for the audio experience.
Its the same thing as people who upgrade their PC every gen. Its utterly pointless unless you have actual workloads that you make money on, that need speeding up to generate more money for you.
