I’ve never had the really high-end cassette decks, but I’m very happy with a JVC KD-S201. It’s very cool-looking. I’ve made wonderful sounding tapes sourced from vinyl, CD, YouTube, etc. Pre-recoded tapes (the good ones - we know how bad tapes can get) sound great as well.
There is virtually no benefit to cassettes. They do nothing better than other formats, and in all but a few areas (they’re not worse than 8-tracks, for instance, and are easier to store) they do it worse.
Perhaps this is just generation-related, but I really love making mix-tapes. One could share a playlist on a streaming platform, one could burn a CD for someone, one could digitize analog-sourced music and then share that music via CD, all of these methods would yield better sounding music than cassettes.
For me, there’s something very fun about the cassette-dubbing process, and something fun about listening to them, something fun about sharing mix-tapes.
I wish I could speak to a Nakamichi, but I’m sure it’s more than qualified for the job. I’m a pretty fussy dude, and I enjoy that JVC just fine.
