Trying to get this thread moving back towards the topic at hand. Commercial pre-recorded cassettes were generally recorded on low-bias tapes at very high speeds with noise reduction limited to Dolby B at best. Many (most?) end users would play the tapes back with Dolby B turned off because the high-end boast made the tape sound brighter when played back. This is sort of like consumer Kodachrome. After all, Paul Simon sang that it "Makes you think all the world's a sunny day". Modern Ektachrome is more analogous to cassettes recorded from decent sources with decent equipment using high-bias or metal tapes with Dolby C and HX used when recording and playing back.
