Reread the past 20+ years of Absolute Sound & Stereophile, then spend time in well-established audio salons with people who have the "ears" experience and are not FOS.
Good list. No one comes close to Nakamichi for tape decks now a days. Some of us still love our old bootlegs and Nakamichi decks may be the best we have. I don't know anything about B&O spinners but techhnics is obviously top of the food chain. The receivers you listed are quality. Not quite MR-78 but respectable in any discussion. Don't let the naysayers put you off. Stand the test of time equipment. You should feel proud to own them if you do.
The Harmon Kardon CD401 cassette deck was every bit as good as the Nakamichi. They only made it for one year, but it had Dolby B/C and HX Pro noise reduction, three heads, and you could bias the deck to match the tape as it had an adjustable bias circuit. When used with metal particle tapes and the HX Pro noise reduction it provided phenomenal recording and playback.
