Okay, I currently use a Nakamichi ZX7 for playback only. My 150 classical London, Angel, DGG, Philips cassettes sit in a box along with many soundtracks and pop cassettes. They sound bad, either compressed, hissy, tonally wrong, etc. However, I made superb recordings on my former Tandberg 310 (it died) without dolby and they were quiet recordings. Better yet, I substituted my Tandberg 9000 RR deck and made superior recordings to the cassettes. I have about half a dozen great sounding private cassettes, some of organ music recorded outdoors in San Diego. I transfer cassettes of ethnic music to CDs. My high end system prefers RR, LPs and CDs to pre-recorded cassettes despite some of the latter being okay. I have 78s with really wonderful sound that mimic mastertape in that alive quality with real dynamics. I had excellent results recording to SuperBeta tape as well. Now I use a Tascam digital recorder. Different from my Pioneer 1500 RR but I've made some professional quality recordings of chamber music by prominent musicians on the Tascam.
I would NOT go back to listening to pre-recorded cassettes in my life.
