I collect vinyl and for me it's not about the sound, but rather about the artifact. Does my vinyl sound good on my system? Yes. But so do CDs and frankly so do MP3. But I like the large format of vinyl, cover art etc. As someone that has released albums, I know how much work and time goes in to such things. It's a piece of artwork you can hold while listening. I dig that.
I totally get that. I guess, personally, that I notice a very large difference between CD and MP3, and vinyl and both of the others. My favorite part about vinyl is that it actually is an analog representation of the recording, and that the circuitry of phono outputs replaces the low end output that you can't fit on the record because the soundwaves are so effing long. :) IMO, the warmth of vinyl through a tube amp is unmatchable via other formats of audio. Everything should sound like that.
