Time to plug in home Stereo

I fired up my old system this past summer. Haven't listened to it in years. I was reminded how I had not heard music so clear and deep since the last time I had it going. Most of my components are from the 1974-75 time frame .... My receiver is high end Yamaha as are the cassette and Cd players both Yamaha - all from the late 1980s. Empire 598II Turntable, Teac 3340S reel-to-reel and my second generation Bose 901s are all from 74-75' time frame.
