Also bear in mind that our power has become far more contaminated by computers on the lines, RFI from microwaves and cell phones, cable TV, etc. In the '80s our power was relatively free from many of the things that plague us today.
I have a passive preamp, built in the '80s, that sounded great back then - now, without power conditioning, the noise from my power lines is so strong you can hear it in the speakers clearly with no source components on. With my power conditioner, the line noise dissappears.
