This is 100W CFA with Input Stage active load (current mirrors) and even lower distortion, below 1 ppm at all frequencies and all output levels . The Loop Gain is about 95 dB at 20 kHz, and I don't know any amp of any technology with so high NFB up to 20 kHz.

If you right click on a post number you can copy the link directly to that post.
Strange. If you did indeed link to the exact post it should work. It does elsewhere e.g. all of Toni's links here work just fine.
I just looked at your last link (RNMarsh measurements):
If I copy the link you have the following. xxxx rather than http is needed to force the forum software to display the url code rather than a url link.

Whereas copy link by right clicking on post 787 produces:

Both have the page number embedded. It's on page 16 for me and I assume page 79 for you. The link should adjust for a given user's cp setting.
For example, Toni's last link in his first post takes me directly to the relevant post which is on pg 34 given my User CP settings. The link is:

Someone with the default or other posts per page setting will see a different number in lieu of the "34".

You need to edit your links like following example.
Original link copy which leads to problems if user has different page size settings:
Working universal link - just remove the (wrong calculated) page number (e.g. "-34") before ".html":
