Oh man! Not since my Onkyo T-9 died in '79. I did buy a Harmon Kardon Citation 18 in the mid 80s and literally never even hooked it up. I think the cassette tape followed by the CD craze got me. Plus I was thrilled to not hear all those irritating ads.
I lived in the Detroit suburbs in the 60s and 70s. There were 4 Album Oriented Rock stations then- Steve Dahl on WLLZ, Howard Stern on W4, Arthur Penhollow on WRIF- man those were the days! I couldn't even burp as low as Penhallows voice was. Irreverent humor, solid B side records, competition for audiences kept the car dealer ads to a minimum. What a great trip it's been to be born in Detroit in 1962. Fantastic cars, great rock n roll, and the HiFi boom all at once. I was in heaven!
