Almost want to buy an 8track player and some 8tracks to do sound comparisons, but too pricey for me as no one makes em. My current setup is a 5 in 1 nostalgia, which plays records and cassetes and cds with bad reviews. The sound is awesome but my power button stuck on after the second use, others had horrible sound for bad connections to speakers, or skipping record players.
A decent 8track player is a fortune, as is a decent oldschool cassette player, as the last decent ones were made in the mid 90's. Also my experience on sound quality was they sucked, my great aunst though has an old double sided 8 track player, with a crapload of double sided 8tracks, basically a normal 8 track with 2 reels of film instead of one, you could play a single in a double but not the other way.
The sound on her high end system was awefull, but the vast rarity of it would sell for a fortune, but she refuses to sell them, sh has sworn for the last 25 years she will convert them to cd and has never done it.
