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

Again, I think we're all talking at cross purposes:

1) Each medium has its own inherent DR limitations. This isn't really much of an issue unless you're really seeking out the limits of SQ. Most of the easily available info on the internet suggests that CDs have a wider DR than vinyl and this was a huge issue for classical music fans and one of the reasons they adopted the CD quickly and abandoned vinyl. My uncle was an audiophile and classical music aficionado. I remember a full wall in his French Quarter home nothing but vinyl when I was a kid. McIntosh components and HUGE Klipsch speakers too.

When I visited him a number of years later all of the vinyl was gone, completely replaced with CDs and there was the CD player, probably the first I ever saw.

I think sever DR compression is found more on CDs than other media simply because of timing. The loudness wars began when CDs were still the primary music media and the renaissance of vinyl was still early or even a ways off.

That anecdote aside, I have no idea which medium has the better DR and don't really care, because:

2) The bigger issue is intentional and extreme DR compression. It crosses all media and if you want to avoid it you have to do the research. There are no guarantees. And sadly, with many if not most new artists it is simply unavoidable whether CD, digital file or vinyl.

I suspect the previous post makes some critical errors in logic. First off the bat, attenuation is not the same thing as dynamic range compression. Attenuation actually preserves the dynamic range, just as increasing the gain preserves the dynamic range. Dynamic range is a ratio of levels. Thus when you turn up the volume at home you’re not getting more dynamic range.

Second, the Unofficial Dynamic Range Database is valuable because it works, and is a reasonably accurate reflection of *comparative dynamic ranges* of a great many recordings and formats. It’s a tool, a quick reference. The reason the database works is because you can hear just how shitty an overly compressed CD or LP sounds. And you can also hear how good a relatively uncompressed recording sounds, too. So, the database by and large correlates to reality. It’s demonstrably Correct. That’s the value of the database - it allows you to dodge the bullets flying around out there. If someone believes aggressive dynamic range compression yields greater resolution or anything else positive good luck with that.

Lastly, it doesn’t take a genius to figure out that vinyl has excellent dynamic range compared to digital, no matter how you slice it, but especially during the past 20 years, when CDs suffered increasingly severe compression. That’s kind of the whole point. Just...look 👀 ...at...the ...dynamic ...range ...data ...base. Hel-loo!
