What is the least compressed signal?


Hello everyone.I was wondering what everyone's thoughts might be about what is the least compressed front end signal? A friend of mine recently told me that radio signal is compressed. So I thought maybe a direct connection to a CD player? Or, since CDs are pretty compressed, maybe a record player? Thoughts?
the reason I ask is, my friend recently gave me a fantastic pair of speakers. And I've been listening to the radio through them. He had a disgusted look on his face and told me I was not using these speakers how they were meant to be used, because the radio signal is kind of crappy and compressed. I would love to use the speakers as they were intended. Meadowlark kestrel hot rods hooked up to an Integra receiver w/ kimbers

What extensive evidence? The evidence you and Geoff keep citing I debunked? That miserably flawed, unscientific evidence ...
Kosst, I’d ask why you are so angry and argumentative, but you’ve already answered the question. I feel badly for you and wish you peace.

Kosst doesn’t have a wife. Kosst went through two. One went to prison for attempted murder. The other died a year and half ago of a heroin overdose. Kosst is a single dad of a 15 year old daughter and wouldn’t get married again

gawd, that explains so much, lol.  and I have to further wonder if kosst = geoffkait and he's just been messing with all of us for the last two years,   especially with geoffkait's 15 thousand post count (this is a thought that I've had for the last few months).
This is why vinyl does not make sense to me.  Too many variables.  How much detail can you really get from a stylus making contact with a groove.   Bet you CD’s contain so much more information.  Information equals detail.  Now factor in the noise with vinyl.

costco_emoji, I will not be totally happy unless milk squirts out of your friend’s nose. I assume your friend is also a high school drop out. You should have listened to your mommy when she told you to finish school. 🤗
