May be of interestI would like to understand how much I can vary the gain of a power amp without causing oscillations
I have already fried a Rotel integrated amp some years ago in the attempt to reduce its gain

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.Hi thank you very much With the last sentence i got honestly scared I heard about 5G but not EMF from TV sets or amps
