What is the least compressed signal?

Vinyl by itself is insanely compressed which is why you need a pre-amp with insane slopes to re-equalize it into something that sounds like music

While we can argue about the dynamic range and noise levels of CD vs. vinyl, I’m afraid this is not supporting evidence. I am afraid Kosst is conflating compression with equalization.

Dolby or dbx both have analog compression methods. The RIAA curve is just an EQ to deal with noise and velocity driven transducers.


As has been noted before, early CDs were severely compressed compared to their vinyl counterparts, so the mastering and the tech both impose the limits we hear.

>>>Actually that’s not true, whoever said it. In the early days the dynamic range of LPs and CDs was about the same for the same album. It’s the later CDs that got severely compressed. Hel-loo! That’s the whole point!  The link to the Stones’ Sticky Fingers I provided earlier today illustrates those points. It also depends on the artist as some artists’ albums never or rarely get overly compressed.

Hi @geoffkait

For some odd reason I haven't the desire to quibble with you over the meaning of "early." 

Carver showed early on that some CD's were compressed both in dynamic range as well as reduced channel separation. Of course, individual CD's varied, and the loudness wars continued even then.

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.

Then why are you quibbling? 🤔
