ps also the common-mode problem?
similar to the ne5534

Looks like a cheap shot from Self.
As soon as the lower impedance feedback network is used the common mode distortion drops away. Whenever a differential stage is unbalanced with source and feedback impedances the distortion due to common mode distortion will increase. Amplifiers should have vaguely similar source and feedback impedances.

Not an appropriate comment I would think. Self took some measurements ( for free ) . He did not cook them up or make them look bad for any reason. Thanks to him for doing so.
The LM44562 is a very good sounding opamp and those measurements go along with it .
One can just go along with it's sound and not bother about the graphs.
Cheers.

This is nonsense.

No.

You mean,what you hear is NOT what you hear?
What you hear may not be what others hear. I can stand more HF distortion than some people simply because with age by HF "personal frequency response" rolls off sooner than a couple of decades ago.
