Best stereo recievers of the 1970's?

I remember walking in to my local Hi Fi shop and looking at the line ups of
recievers.Pioneer,,Jvc,Sansui,Kenwood,Luxman.I loved the Sansui 9090 db
but when I heard the Luxman (don't remember the model number) in the late 70's it was the best I've ever heard at the time.
