Late-production cassette releases on good tape stock, some with Dolby C encoding, can be very, very good. I still have the Advent CR70 classical cassettes that I went off to college with in '77 and they still sound great. Toughest thing about the format today is, just like vinyl, it is a lot more enjoyable to just settle back and play an album (or a side), skipping around (even with the decks that have the track search capability) is just not convenient. It's fun that the 20-somethings in bands are tracking down old working decks and using them to play their new releases - could lead to something, I suppose...but still hard to see a new era of deck production happening.
