The Black Hole......

It was conditonal on TNT's implicitely given assumption (i.e. that sampling at Fs at 192 kHz or even above) solves any problem that might exist. While that might be true - again under an assumption like that microphones are used that offer extended bandwidth - it will not help in this regard if not distributed in such a format that preserves the possible benefits.

And to the extent we spend our money on the 192+ will increase those and encourage more. Already better mics are being used now.... Some new condenser types that are flat, low distortion, wide BW and can take high spl plus are moderate costs only.

Yes, you can take shortcuts and pick up some information without a background in a subject, but it has its limits. At some point, you need to know the basics to be able to move ahead and even communicate accurately.

It's like trying to discuss more advanced math when you haven't taken Algebra. Without that foundation you can probably be explained some concepts, but it's just not going to work and you'll be asking some strange questions. As someone who's learning style is more top-down rather than bottom-up I can empathize, but sometimes there is no shortcut.

Yes, I understand my position, but if just one of my strange questions makes someone who does know take pause to look at something in a different light, then I suppose my unintelligent babbling isn’t so bad?
Besides.....if I don’t get swatted with a newspaper every now and again, how am I supposed to know not to pee on the rug! 😀

I only mentioned the slew rate thing because it kept popping up with digital brick wall filtering and how it’s tied to Nyquist limits etc.

Actually, it does matter (SR) as you do not want the input signal Tr to be faster than what the amp input can handle. You dont want to drive the input into Slewing condition.

Yes, that’s the context I was referring to, disruption of the input signal.
 
What makes anyone think hi res sound is solely a function of audio frequency response? The real world is more complex than simple models where every result/observation/event has one and only one underlying cause.
The discussion here is just whether 96/24 or higher improves on 44.1/16.
And the only proof is in controlled listening tests that for some reason is avoided.
We can talk it to death and never come an inch forward.
If the matter was that easy to prove mathematically, it had been done long ago.

On the other hand various listening external test, attempting to show that a difference exists, were not conclusive, so if a difference exists, it must be small.
When Hi-Res was so much better as mentioned by some, it would have been a discussion of the past.

I’m just talking about the medium that cannot be blamed for bad recordings.

Hans,
Are you serious that you don't know why such tests are not done? To do double blind in a live setting takes at least two experimenters. One that works with the test subject and one that does the switching/control in isolation.

In addition, IME how hi res compares to CD depends a lot on the hardware used: DAC, power amp or HPA, and speakers/headphones. I have had systems where experiments indicated that DAC was causing most of the difference.
It means that the equipment has to be qualified for the purpose of answering the experimental question, whatever it is to be.

In other words, it is complicated, time consuming, and likely subject to lots of criticism if the results do not align with people's preconceived expectations.

Nobody in this thread has volunteered to take on a project of that type, and almost none have qualifying expertise to run an experiment of that type. What people are usually willing to do here involves a little sitting at a computer. Producing a recording ending up of one selected cymbal hit took me hours to do from start to finish by the time the mess in the living room was all cleaned up. I can't imagine taking days to work on a listening test not to mention recruiting volunteers to help. Nobody will even come here to do a test listen, the most bizarre excuse being worry about being 'groomed' whatever insult that was supposed mean.

Now you know why I don't do the listening test you want. Hope that helps 🙂

But spend on music is declining. Streaming is the growth area. Will MQA rule all or will some streaming sites differentiate on doing higher bit rates?

I’m not sure if a lossy format could overrun the purists wanting their music as close to the source as possible....Tidal seems to have the monopoly on MQA unless I’m mistaken?

Qobuz is stumping unadulterated flac (up to 24/192) streaming.

You are making things much more complex as I had in mind.
No DBLT or whatever, just a personal impression.
When someone can propose a representative 96/24 HI-Res recording, I can take one track, brick wall filter it, but leave the format in 96/24.
And I can make a second version, also BW filtered but now limited to 96/16.

So each version makes one alteration at the time.
Each of us can play these at home and give his/her impression.
It’s a step in the direction that could already give some indication, nothing more nothing less.
When nobody can hear a difference we are done, although I don’t expect that outcome.

You took that as an "insult"? hilarious, well, you'll get over it.... As for the rest of your post, why did you waste your time repeating your excuses for not doing something or other? Can you point to any evidence elsewhere instead? I asked Jakob but he neatly sidestepped the question 😉 Or perhaps he didn't realise it was a question, that's quite possible, I should have been much much clearer 🙂 my fault entirely.

I won’t .
Note that a third 'L minus R' loudspeaker works well with a lot of stereo material (make it switchable).

That sounds interesting. Do it.

But, if some hear difference and some dont.... then what?

Now if there was a big cost savings to listen to a design for 16/44 vs 24/192 etc... then maybe.... maybe... for some portion of the public, sell the lower cost one to make to them.

Today there is no significant cost difference for any format above 16/44. so, as a practical matter, you just make it fit all and use the 24/192+ Even if only 5% of public heard an improvement. Just do it once and make everyone happy campers.

It may be 5% but they are really a vocal 5% (or what ever small number you like) and influence buying public and sales.

Its here. Its done.
