chakster,
I understand the concept of master tapes and them not being for us and vinyl being some sort of our "original" although it is not truly original. I approach it that way, too, but original it is not.
"...created by musicians for us (buyers) at the time when it was actual for them."
Historically true but, if chasing the true sound that artists from then thought we would be hearing, we should not be buying turntables and cartridges now. Much less multi-thousand-dollar cartridges which are surely way better at extracting whatever is on the record. Artists in 1966 were not expecting us to use such things. They probably did not even exist. We should be playing on "period instruments". 1960s record on 1960s turntable etc. All else, following the logic "artists made it that way for us" may be overshooting the target.
"Why do i need a copy from my record if i can play record ?
This is much simpler, don’t you think so ?"
In your case, I would say that a good digital copy may prolong the life of your record. I assume it is much easier to buy fancier and fancier cartridge these days than it is to buy records that you seem to prefer.
It is much simpler to play digital files than records. There is really no comparison. I am not saying that the overall experience is better, but it is way simpler.
"I can not take seriously anything in digital, i want an original phisycal media format (vinyl)"
This is where you may be doing yourself disservice. Explore a bit. I am not saying you should stop buying records, but see if digital these days is as bad as you remember. Not your iPhone, of course, but some more audio-focused set-up. I also want everything in physical format, even if I put it on a hard drive as soon as I buy it, but that is a preference based on growing-up and what not. It is not some fantastic advantage.
"Digital have no fun at all, it’s so boring even in top bit rate and high resolution."
Most of the "younger" people out there would disagree, if they ever cared to consider thinking about it. As far as higher resolutions go, I would disagree. It does get quite good.
"Again, this is cultural thing, not just a fidelity."
That is true, it cannot be more true I think. That does not make digital horrible and those preferring it having no taste, though. I prefer the idea of records, convenience of digital, and sound of whatever I have around.
"I had more fun with cassete tapes many years ago than with all that digital files today."Didn't we all have more fun with everything many years ago than we have today? Nostalgia can be a powerful perspective-changer.
