Can't take more than half an hour or so before having to switch to

Surely being a sound engineer you should be able to 'put a finger' on
what sounds different?

Some sort of higher frequency "edgeiness" and sounding if it's being
driven into a 5:1 compressor fairly hard.

yeh. Know what you mean. My Pi based internet radio tuner has the same
on classic FM. Oddly, on Radio 3 it has not.

My guess is they are simply using less/more bandwith.

MP3 streams are not lossless.

important for the State to use all of its powers to repress dissent, for
the truth is the mortal enemy of the lie, and thus by extension, the
truth is the greatest enemy of the State.
