+1 for late 70's early 80's Sansui, Luxman, Accuphase. for Japanese anyway. built like tanks very good parts and a very good rep. the Sansui AU series were stellar but prices are climbing fast in the used market. The higher end Luxmans are all good (up to 1985) and if you can find a Class A unit grab it if you can stand the heat they are stellar. All the Accuphase stuff is a great buy, maybe their earlier stuff is a little on the homely side but inside they are up there with the best.
