I do agree with you, HighFigh. I used to record on a Nakamichi and sync it with the CD, match levels and switch back and forth. I certainly could tell which was which, but you did have to pay close attention to tell the difference.
As far as commercially available cassettes, they sucked. I think it was important to record and play back on the same machine.
At that time, HK, Sony, Kenwood, Teac, Wollensak, and Technics all made some nice solid units, but none could touch the Nak for SQ!
Build quality was a different story (at least for my Nak. The Dolby C crapped out within 5 years).
