I dont think that the Cassette is massibly returning.
May be this is similar to "Vinyl return", with excepcional costs and regular quality of new copies compaired with old ones. Only a return in "fanatic mode" by new people, or nostalgic remember by old ones.
But, going to basics... -and blank the fact of I m a very... very fan of CD tech how an advanced in time and disrupt format when it born at end of 70s-...
I believe that (for equally duración and quality in mobile situation, cars, outdors, etc.), "the little box" (Compact Cassette), is most reliable, practical and robust way of carry music, -cause: CD is more "destroyable" and digital ones... well... in this format problem is not the content but interfacing devices, most of these literally "discartbly" ones in "undesirable yard situation"
In fact, pirate SW portable emissions may be a good example for needry of Cassette return
That's unlike vinyl which had its dynamic advantages, or CD's which have their capacity advantages.
Yes, but... dynamic vinyl advantages are more commonly dependable of mastering audio process, is not an intrinsecall format advantage. Good times of mastering maked good vinyl and, logically, loudness war times maked bad CDs from mid nineties... But, this fact is also true if invert.
May be you refer to more reliably (sub and suprasonic) frequency response of vinyl (majorly inaudible), compaired with Nyquist 44100/16 cut of CD, but this fact crashs with cross pickup position read angle (that destroy fidelity from mid of 33/12 inches record sides to end), and horrible signals to noise ratio compaired with CD or digital ones, although the 16 to 19 KHz response of cassettes (talking of CR2 of Fe tapes and directly function of quality of recording deck), of course, is not an amazing feature of this format...
