I read Coltrane2's post, and disagree strongly about the 'warmth'.
You are talking about two completely different animals, analog which is the actual transfer of physical sound to electrical impulses. But it works the same as your ear, which converts motion/sound waves to electrical impulses. All digital formats use a binary code and assign values to every note, then the decoder converts them to electrical impulses which you hear though your speakers or headphones.
After mucking about with all this stuff for a decade+ now I feel comfortable in saying a vinyl recording made before the 90's of all our old classic music have a warmth and feel that is missing on the digital counterpart.
I could fill this thread with individual examples but that would take too long. (There are also some top notch CD's as well, Supertramp for example sound excellent on CD.)
And I have never had a problem with portable music, I don't mind convenience and own a Walkman cassette player, my problem comes with corporations forcing all of us to use lossy formats because it's easier for them to make more money.
I want them to continue to offer HQ digital files and Vinyl if possible, after all you can always convert them to whatever size files you want later but you can't do the reverse a lossy format is a lossy format.
Mentioned this before but will say it again. Many experts with the best equipment have done extensive work with the analog/digital signals. The vinyl rips I have on my HD's are amazing quality. Most of them are done at 24-96(DVD standard) because they felt the 16-44(CD redbook) was not capable of capturing the information in a vinyl recording's groove. Some others' have gone a step further and done 24-192(Blu Ray) rips because they believe it is the closest they can get to preserving an analog record which the CD format just can't do to their satisfaction.
