There is nothing wrong with preserving especially your analogue vinyl sound onto cassette. It's just a fun side road to this hobby. I have two nice three head cassette decks. A mid 90's upper end Yamaha KX-930 and a mid 80s's top of the line JVC DD-VR9. Both feature full computer test toned auto bias, level and sensitivity setup. Using good cassette stock especially type II or type IV or even a good type 1 can give me near indistinguishable recordings of vinyl from my LP's themselves.
The dancing fluorescent meters looks cool too.
