What makes tape sound better than vinyl ?

@orpheus10  That’s all well and good but in the OP he says he is copying vinyl onto cassette. So we can eliminate reel to reel from the debate. Fair enough? The OP question is a general one, is there something about audio cassette that would make a vinyl copy superior to the original vinyl, you know, sound quality wise? We don’t have to compare audio cassettes to reel to reel or vinyl to reel to reel.

On the contrary, this thread is about open reel decks and tape, I only mentioned cassette as an example of a 'mini reels'. 
We can compare anything to anything.

Fair enough. But that’s not what your OP was all about. A cassette is a mini reel? Interesting.

I have to take issue and disagree with your basic premise. Tape doesn't sound "better" than vinyl it sounds different, you may prefer those differences but it doesn't actually make it better it's just a matter of preferences after all there are people who like the sound of Bose speakers , and that doesn't mean they sound better. Just saying.

I would not say that is true and it definitely depends on the units and setup. So, no I would not say that is definitively true. Both can be excellent, both can be ordinary, both can be bad, and both can be a pain to setup.
