I'm not upset I bought the 444 in 79, and I'm not at all upset I traded it in. Audiophilia is a journey, and I'm extremely happy with the musical enjoyment I've gotten out of my system over the years.
The OP asked for turntable guidance, i'm not sure your post could help someone if you tried Luxman in 1979, now we have much better phono stages, speakers, cables etc.
I don't need, or even want two tonearms on my rig at the same time.
People have more enthusiasm at younger age I believe. However, It's not necessary to put two tonearms on Luxman, it can be used with one tonearm (any size).
I'm glad you enjoy your system, but it doesn't make you look good to try and attack people who don't agree with you.
I never attack anyone, simple facts is what I post here, especially when other people asking for guidance. I don't like belt drive turntables as I said, but we have many more people who do not understand what is a high-end direct drive and posting nonsense about them, some models are completely unknown for them as i can see reading this forum.
An impression from a listening session made in 1979 is not valid today, many younger audiophiles re-discovering vintage Japanese direct drive and happy about them, prices only goes up. Direct drive perspective like almost everything in audio was a way different in 1979 than today (in the digital world and belt drive turntables) @xaak
