Sorry, I'm late to this conversation but... TAPES YES!! When done right (or even wrong for that matter - intentionally or not) it does such a justice to the sound. There's definitely a loss in the sense of "the moment" when playing back digital files that were recorded digitally. This effect is obviously exponential when talking about chip music. I mean, a lot of us were introduced to this kind of music as it was coming out of some crap built-in mono TV set. AM I RIGHT!? Now I'm all jazzed up! There was a release in the last year or so on bandcamp that featured a cassette modded with an mp3 player inside. You could listen to it as a cassette but it also had a headphone and usb jack and came with the album of the group pre-loaded. By the time I found out they were totally sold out. Check it out.
I got the cassettes, cases and inserts for The Wave printed from A to Z Audio.org. They have a bunch of options for bulk and short run tapes - stuff like tape color/foil, length, label printing, on-tape printing. You can also just order blanks from them for a good price. I know the website is funky, but from my experience they're totally dependable.
