Hi wolf_garcia -
I have been around hi-fi literally for almost seven decades; my dad sold and repaired the stuff for a living, so I can't remember a time when stereos were not part of my life. I was testing tubes for my dad when I was 5. My statement that stereos back then were 'tuned for analog' means just that, there was only analog. So yes, LPs, tape, and radio were the only things on the menu at the time. There were no CDs, SACDs, Blu Ray audio, streaming, or HD anything.
I don't think that you, myself, and the original poster disagree here. We have all recognized that today's stereos sound different, with the nod being given to today's stuff as sounding more accurate. There is a YouTube video out there with Paul McGowan (PSA fame) saying just that and to him, it's not even close.
To some, the vintage sound is worth chasing, but to me that is nostalgia talking. I started out with Philco & Voice of Music equipment. Graduated to SONY and there must be at least a dozen or more brands that have made their appearance since then. I chased vintage 22XX Marantz receivers at one point, but outside of FM radio, they didn't quite do it for me.
One of my buddies had Sansui equipment that sounded nice, better than my SONY. Another buddy moved up from a KLH compact to a McIntosh/ Bose 901 combo (his dad had a cash business), but truth be known, I liked the KLH better.
And so it goes. No reason to shade stereos from 40 and 50 years ago. How and what I listen for has changed dramatically. I think you would agree.
