The thing with vinyl is that there is a tone which is not present in the Cd. So that difference is not 10%, it's 100%. I still have most of my metal on CD as it was the only way to get the music. Also CD is a compression standard. They sat around and thought out what Redbook should be. The bass on vinyl is just better if it has been done right. Sadly some vinyl is just not mastered right. The only time you know is to read reviews before buying. Some vinyl is crap never getting to the true potential the format offers. I purchased Black Sabbath number one in 1976 on vinyl after listening to the cassette for three years earlier. I didn't even have a CD player till about 2000.
What's very sad about this is technically speaking, CD does bass MUCH better than vinyl since there are inherit limitations to what a cart can do (in fact its why I believe sub-bass gets removed via a high-pass to deal with it).
But you would never know it because of the Loudness War.
I have a lot more to say about vinyl and tone but I'm gonna leave that for the site.
Bottom is this though (for me): CD's if mastered right can sound glorious. How many metal CDs are mastered with maximizing fidelity? Not many.
Btw Mr Moose, have you heard the new Torture Division in HD?
If not, please click that and download, listen, enjoy!
