I did a listening test comparing direct DSD to 16/44.1 and couldn’t discern any differences. If you’d like to try that yourself, I can tell you how to set that up.
I already tried that. To me and my DAC, PCM and DSD sound different and DSD is always quieter, but not necessarily better. Both are equal quality-wise.I did a listening test comparing direct DSD to 16/44.1 and couldn’t discern any differences. If you’d like to try that yourself, I can tell you how to set that up.
Do you try level matching, ie either raising the volume of the DSD or lowering the volume of PCM so they are equal and then blind testing them? All the controlled tests I've seen don't find a difference in normal listening.I already tried that.

"HiFi Video" recorders did. They recorded frequency modulated audio with rotating heads. But at that time digital audio was already upcoming.
I did. I increased the volume of my AMP so that the DSD files are the same volume as the PCM files. Keep in mind even PCM files upsampled to DSD have a lower volume (I gave it a -6dB gain). Overall the DSD sounds flatter and more "analog" while the PCM has more "oomph" and the instruments are a bit more "in your face". I did this test with Audirvana.Do you try level matching, ie either raising the volume of the DSD or lowering the volume of PCM so they are equal and then blind testing them?

I saw an interesting video where using an app someone played two files on opposite phases. If they cancel each other out and you hear just silence or hiss they are the same. Can’t remember the name of the app but he used it to show that 24 and 16 bit recordings are identicalEqual quality is equal. You can always turn up the volume a hair. If you properly level match, all differences will disappear. High bitrate lossy, CD quality sound, HD Audio and DSD are all capable of being audibly transparent. To human ears, they should all sound the same unless you're doing something wrong.
There are four components to a controlled listening test. I did all three of these when I compared DSD to 16/44.1:
Level matching: Both samples were set to an identical level. Humans tend to perceive slightly louder sounds as sounding better, even when the louder sound is the exact same quality. Even differences as little as a half a dB can make a difference. You can't just ride the volume control. It has to be calibrated carefully.
Direct A/B switched: Human auditory memory is very short. For similar sounds it can be as short as a couple of seconds. If you want to compare similar sounds, they need to be racked up through a switch box, playing the exact same music in sync so you can just flip a switch back and forth and directly compare them.
Blind Testing: Expectation bias is real and it is unconscious. You can't will it away. The way to eliminate it is to focus entirely on the sound and remove any other identifying information about the samples.
Multiple Tests: There is always an element of dumb luck or chance involved in picking one sample or another. To eliminate that, you do multiple rounds of test and average them to see if it reaches the level where it can't be blind chance.
Do all four of these, and you will know to a high degree of certainty what the truth is. I've done this. I know. That is step one. Step two is making your results repeatable for other people. Take care of step one and then we can talk about step two.

Is the wrong takeaway from this to say "well, he does prove that higher bit depths have the same "amount" of music in them, BUT he also proves higher bit depths ARE superior because they have less noise in comparison!"?That’s it!
The only thing I took away was what I originally stated, ie that by cancelling each other out when played back in opposing phases proves that no additional info is there. Not sure what else he tried to imply.Is the wrong takeaway from this to say "well, he does prove that higher bit depths have the same "amount" of music in them, BUT he also proves higher bit depths ARE superior because they have less noise in comparison!"?
I also wonder if this can be applied to cd vs. vinyl vs. mp3.The only thing I took away was what I originally stated, ie that by cancelling each other out when played back in opposing phases proves that no additional info is there. Not sure what else he tried to imply.
It could be easily applied to cd (lossless) vs. mp3. However this test is meant to check if the compared signals are different and since pretty much everyone knows lossy has to be different compared to lossless (that's why it is called lossy in the first place) the test wouldn't reveal anything that we didn't know in the first place. CD vs. vinyl would be harder to do because it would require some actual hardware that can do the phase inversion, gain match, and summing in the analog domain.I also wonder if this can be applied to cd vs. vinyl vs. mp3.
