I still use the equipment that I bought in 1971 with a upgrade in 1975. Started with a Sansui 7000 receiver, sr4050c turntable and two sets of s109 speakers. I changed receivers in 75 an got a Rotel ra 1412 amp and rt 1024 tuner. Speakers have been reconed twice in that time. I did add a Paradigm sub to the mix a number of years ago. I use them daily and have all these years.
