You never stated this, ever?
Correct. I never stated there "are zero commercially available music recordings on any format with stereo bass content below 80 Hz" or that I "had to revert to recording (my) own content" to get stereo bass below 80 Hz.
I’m not sure why you keep insisting that I said that, but you’re free to believe whatever you like."
My point or question is what did you mean when you posted this?:
"It’s amazing how just how common the "all bass is monophonic" canard is and how reluctant some audiophiles are to reject it. After all, it can be resolved by listening, especially if you make your own recordings."
Specifically, why would you state: "After all, it can be resolved by listening, especially if you make your own recordings."
It makes it sound like you couldn’t just play any commercially available recording that, according to you, generally have recorded stereo bass below 80 Hz. Then you don’t just state the question over whether stereo bass below 80 Hz actually exists or not can be resolved by listening to any commercially available recording, but you qualify it by adding "especially if you make your own recordings."
I’m not even sure what this means exactly. What are you recording? Commercially available music from another source or your garage band live? What recording device, what recording format, what is the format’s recording resolution and frequency range capability?
