Maybe I’m wrong, but if your cassettes sound better than your turntable, then something is wrong with your vinyl set up or hardware. Cassettes can sound good but ultimately I find vinyl better. Now, if Dolby SR was used for all cassette mastering and releases that would be very interesting, indeed. The problem is it wasn’t.
I did an enormous amount of live to two track analog recording back in the day and cassette was only used as a convenience not as SOTA. Hey, but it worked and I made some nice recordings.
