I thought that there was pretty conclusive evidence that a CD or uncompressed (file size wise rather than acoustically) digital format matches or exceeds vinyl in terms of reproduction fidelity. Compression in an acoustic sense is more a case of current (annoying) production practices rather than the medium used, and, as has already been mentioned, the RIAA standard for vinyl recordings includes compression and decompression of the bass anyway.
Some people might prefer the sound of vinyl over CD etc, and it may indeed sound 'warmer' (I quite like vinyl myself), and this is perfectly valid, but to claim that it is a more accurate reproduction seems unfounded. The other thing with vinyl is that it inherently degrades every item you play it. It might sound wonderful the first time, by the 100th time it won't sound the same.
Personally I am more interestinged in listening to the music rather than the quality of reproduction.
