Oh for goodness sake fella's...
Having sold most of the decent cassette decks out there I can say that unless you have a top line Nak or Teac equivalent (the Teac 8000 series was superb around the mid nineties) you can't even talk about cassette being good (and I currently have a DRM 34HX *in the loft!!!!!!!*)
Denon's wow, especially when they age and the head-block tension springs stretch a little. They have a response peak at 14KHz followed by a nosedive after 15KHz - and "you lot" complain that CD doesn't go over 22KHz or so. Gives crisp playback but dull recordings when played on other decks.. The tapes lose treble, especially low level stuff unless it's a metal formulation..........
Seriously, GOOD digital is actually more musical than much analogue IMO and you have all that extra clarity there too. My CD player can give a "walk-in" soundstage on the right recording and if I want a more "organic" portrayal, I do it with the speakers - oh sorry, I recently did.................
All I can say is, I've not used cassette at home since my son was a toddler eight to ten years ago and I haven't missed it one iota. I owned most of the big Naks at various times too, including a CR7, Dragon, 682ZX and both an original 700 and a later 700ZXE. Give me CDR any time
