Hi thank you very much for the very valuable link
The main problem for me starts at the source and its V level
I listen to various digital sources with different output
No vinyl
Imho a very good volume control followed by a unity gain buffer should be quite doable
This can be achieved with very low THD and good driving ability
When even a small voltage gain is introduced the THD goes up and gets amplified by the power amp
So for me the problem is the line stage
I have to fix that
After that I can pass to the power amp selection

I had a '5G' phone for a while, until it broke and I went back to 4G / LTE, and the difference was curious. I actually found the perceptible radiation to be much lower with 5G. LTE produced a 'burn' sensation like a combination of radiant heat and rheumatism, which was persistent and annoying and put clear limits on the amount of internet time I could tolerate. The 5G phone didn't have that. Maybe it still turns our DNA into obedient nanobots, but for normal daily use it was better.
