psag,
I think I understand what you are saying regarding enjoyment from your old system which is not as high tech as your system today. I have had and heard a few systems, that even compared to your old one, would be considered totally basic, that just produced music beyond all expectations. Of course memory can play games, and they are long gone and replaced by much more expensive gear.
For example, when I was living in Huntington Bch, CA I answered an ad from someone wanting to sell his stereo equipment. The system ended up being a non descript Sansui receiver, Cerwin Vega speakers with 12" woofers and a Denon CD player. Truly the sound was enchanting and everyone who heard it would just out of nowhere comment on it. Gave it away to a friend.
Another system had a set of Quadraflex speakrs. However this particular model of Quadraflexs was voiced, it just sounded great.
Just reminiscing, thanks for this thread.
