Not a problem with solid state you see.

PSRRs are typically in the 120dB region.

** Really?


On what planet is that ???


Earth in 2007-2008.

TL071 = 86 dB typ


NE5532 = 100 dB typ.


Both 30+ years old designs.

" PSRR and CMRR exceed 120dB (typ) "



** Totally irrelevant.


????????????????????

Modern pro-audio gear is CHOCK full of them.


Yes, but most modern gear is low end and/or based on legacy designs.

You LYING piece of ****.


Ignoring the performance of SOTA equipment that is on the market and
generally available is deceptive.

On balance, why one *needs* 120 dB power supply rejection when $0.25 and
0.50 cent regulator chips produce DC power with just a few millivolts of
noise on it, makes this discussion kinda moot.
