wow, analogue fanboy. I have not seen one of those in a while.
seriously, analogue formats can't even come close to the convince of an MP3 player. 1,500 songs plus photos and video's on a player that's has 24 hours of battery life and is the size of a single TAPE, no contest what I'd rather travel with. The whole argument of sound quality is worthless anyways though unless you have rediculously expensive speakers/headphones anyways, going from shitty little ear buds and $10 drug store headphones to nice quality DJ/studio monitors produces orders of magnitude more improvement in sound quality than changing formats (of course if I'm taking BART or something I'm not bringing my good headphones with me anyways.)
And if you ARE in your home and you DO have high enough quality stereo equipment and you're dead set on using analogue, why not just use Vinyl?
