Let me try and explain it in simpler terms......
I USUALLY listen to my music in stereo - most often on speakers - but sometimes using headphones.
But, especially when I use the computer, sometimes I try out one or another processor - like the new Dolby Atmos plugin for Windows or the Dolby Headphone plugin.
And, sometimes, I decide to make some sort of adjustment - like removing noise from a poorly re-mastered old recording.
And, sometimes, I listen to my music on other equipment, either or loan or at other folks sites.
Therefore, I need my music collection in a form that I KNOW will work AS INTENDED for any of these purposes.
I may put some files on a USB stick to play in my car - and, for that, I may use lossy compression.
However, it would be much too complicated and time consuming to have to run a whole new series of validation tests on some lossy format every time I try a new player program...
And, since we all know the sort of measurable changes lossy compression causes, we also know that the result WILL be significant differences with at least some processing.
And it would be a very expensive mistake to purchase files today in a lossy format - and then find out that they don't decode properly on the new player program I purchase tomorrow.
All of these problems and risk will be present if I use lossy compression - and I avoid all of them by NOT using lossy compression.
If, every time a new decoder, or a new piece of gear, seems to sound a little unusual, I have to get out the lossless copy to confirm where the difference lies....
Then I've found it's much easier just to use the lossless version to begin with - and avoid the possibility of having to.
As far as I'm concerned, the "cost" of using lossy compression, in terms of issues like this, is too high.... and the benefit is trivial at best.
To be honest, I don't care what the engineers or musicians can hear; I only care about what I can hear.
I also have a strong suspicion that the engineers and musicians may not have actually personally auditioned the specific MP3 version they're offering to sell me on Amazon.
(Therefore, the fact that "many of them have difficulty hearing the difference sometimes" isn't really relevant as applied to a particular album they didn't hear.)
And I know for a fact that they didn't try that five-year-old album on the new Dolby Surround Upmixer (which is what you get on all new Atmos AVRs - but didn't exist five years ago).
Or, to phrase that differently, an actual lossless copy of the content is "future proof", while we can't know if the lossy version will work the same on something new until we try.
(We can be sure that 'the original will work like the original"; but, with any lossy copy, we can never know until we try it.)
Again, "difficult" doesn't count... and neither does "maybe".
When I listen to a song I want to KNOW FOR SURE that I'm hearing what I should be.
Something that's "probably the same as the original" isn't good enough...
And neither is something where "I think the differences will be difficult to notice"...
To me, saving a few cents, or a few bytes, is an awful high price to pay for all those doubts.
And, yes, I've heard one or two studios, and many of the top manufacturer's "showcase audiophile systems".
And, yes, many of them sounded very good.
And, yeah, a few of them actually didn't sound very good at all (but I'm sure somebody thought they sounded great).
For the record, you will NEVER hear me make any claims about "how things sound on expensive systems" - one way or the other.
(there is some "very expensive audiophile gear" that is nowhere near accurate - and nor would I listen to it.)
Are you honestly suggesting that the studios you work for plan to start releasing all of their products in lossy format?
After all, if NOBODY can EVER hear the difference, then that would seem to be the obvious thing to do.
However, if they're not planning to do so, then I guess they agree with me that the lossy version really is "pretty good but not quite the same".
I have two direct questions for @gregorio....
Have you discarded all of your lossless recordings and replaced them with perfectly adequate lossy copies?
If not; why not?

1. Huh? How self-contradictory is that?
2. None of this makes any sense. If you want to alter the music then of course it's not going to "play exactly like it should" and "as it was intended". Lossless is not the simplest OR "most reliable way of achieving that goal". If for example you want surround sound, a far better/more reliable way of "hearing the music exactly as it was intended" would be to buy a recording actually mixed in surround, in say Dolby Digital (5.1) which is a lossy format, than upmixing a lossless stereo mix!
1. What about the musicians and recording engineers who actually created the recording (or any other engineers or musicians), could none of them tell the difference either? The assertions about modern high bit-rate lossy codecs is not solely based on what an "audience with no experience" can or cannot discern, it's also based on what engineers (with a great deal of experience) can and cannot discern. Not for the first time, your analogy/anecdote is NOT applicable and if anything, to the moderately intelligent/logical person, it actually indicates the exact opposite of your own assertion!
2. You agree with whom? It's only your assertion that lossy files "are often sufficiently close to lossless to be difficult" to distinguish, therefore you're only agreeing with yourself!
2a. But this isn't the "What KeithEmo is Convinced of" forum! Especially when "what KeithEmo is convinced of", contradicts the actual evidence and even your own evidence! According to bigshot you've actually done the thread's title, you've actually tested for yourself the audiophile claim and failed to discern a difference. So you not only failed to support the claim but actually added to the wealth of evidence which provides very high confidence that the claim false, yet still you support the claim and are "not convinced". Why is that?
1. Indeed I would be amazed, as in 20 odd years I've never come across a single person who could easily tell the difference. Even in the late '90's, when the lossy codecs were far less effective, it was NOT easy to tell the difference!
2. Nope, even with "seriously expensive kit" it is never "immediately apparent". Have you ever actually heard "seriously expensive kit" or have you only ever heard extremely cheap or fairly cheap kit? I assume you've heard average consumer systems and probably one or more audiophile systems, which at less than about $100k are fairly cheap but have you ever heard a "seriously expensive" system, say a $10m world class recording studio? Fairly often we get audiophiles coming here, making claims about "expensive kit" but it's both nonsense and hypocritical because typically they haven't got the faintest idea what an expensive, exceptionally good system actually sounds like and assume that everyone here is even more ignorant than they are!
