Many people don't realize
that AM radio's bandwidth is limited to 10Khz

That is why most records made in the 60s and earlier sound like they
do. They were mixed to play on the radio. It wasn't until "hi fi" LPs
came around that you started getting decent sound. Even those got
"remastered" for CDs. When you play old tunes on a good system that
limitation becomes immediately apparent. I doubt the original source
material even exists to remaster them in a lot of cases. I suppose
they can try to expand the sound digitally but it will just be a guess
about what it was supposed to be.

I don't think the old recordings were purposely mixed to play on the
radio. High quality recordings were being made in the 30's and 40's.
They just don't sound very good on AM. Also .. that 10Khz bandwidth
is really only 5Khz available for audio modulation. The 10Khz is the
total of what the allocated spectrum is above and below the carrier
frequency. So, you are only hearing up to 5Khz.

That is what I hear quite often when talking about top 40 hits.

I agree there were recordings at higher quality but they were not on
AM radio that much. In those days FM was "long hair" music and the
kids had crew cuts or flat tops.
You can really hear it when you listen to the Brill building music.
It is very "thin".
