I have a simple Nak deck, and love it for the times I use it (have quite a few cassettes from ‘back in the day’).
But really, I find it isn’t always so much the deck (I’m not underestimating it’s importance) but rather the quality of the tape. Or, if a retail production tape, when it was produced. And if the the tape is not damaged in a variety of ways. Personally I have found the ‘production’ record label offerings fro the mid/late 80’s into the 90’s most often are pretty darn good. I have very few retail tapes from the 70’s that sound anywhere near as good. In terms of blank tapes, I only used Maxwell and TDK ‘metal’ tapes, and if in good shape, still sound very good. But they cost a fortune today.
In todays world, (unlike in the past when you had to record vinyl to play in your car, as example), I’m not sure recording to cassette tapes is preferable to either vinyl or a good digital rig and streaming service. But, as I say, I have quite a few good record label tapes I still enjoy from the ‘golden era’ of tape production, and almost always prefer them to CD’s of the same period, but almost always less so than vinyl.
