I think it must have first occurred to me when my step-father replaced the Pioneer SX-3600 Flouroscan Receiver and Dual 1215 turntable that was normally in our living room with one of those horrible Aiwa (because he felt cd's were "the way to go") units with the dual cassettes and three disc cd changer and a bunch of flashing lights. It was a horrible thing to use and sounded horrendous. I sold both components (as at the time I was in the process of moving out of the house and had my own stereo) to a friend for $50.00. He still has them and they are working fine, as for the Aiwa, it died three years ago. He should have just bought a cd player for it. Of course this is a guy in 1970's photos was wearing leisure suits (something my father never did).
As bad as the Aiwa was, the ones now are even worse!!!
