The title says it all: Vinyl, CD, MP3, anything else? What is your favourite record format?
I personally prefer the CD. If you need any digital version of your album you can alway rip it, but vice versa you won’t get a CD as good as the pressed version if you burn it using lossy formats like MP3 or AAC. Vinyl has - theoretically spoken - an infinite resolution while CDs are restricted to 16 bit / 44.1 kHz (Seen this way, the CD is a lossy format ;)). Vinyl is a nice thing to have, especially when you like cover art, and of course its sound, that magic aura when played… But it is not as versatile as the CD, and it is veeery expensive to get good sound quality out of vinyl records, the prices of good record players are really high… Even vinyl records themselves are expensive. That breaks the deal for me, though I often enjoy listening to it when I’m around at people who have a nice sortiment and good equipment to play it.
So, I usually buy CDs. Well, there are some exceptions, like the Phantom Antichrist single that is not available on CD, but… yeah, first choice is the CD version of an album.
