So, you're entitled to make fun of anyone whose behavior doesn't quite match your value system. I think that demonstrates the point Hal was making.
By your definition, most of my system is anachronistic--my preamp was made in 1979, my tuner in 1991 (tuner? TUNER!?), my digital parametric equalizer in 2000 or so, my CD player in 2002, my speakers in 2005, etc. My amp is relatively new and fairly modern, and there are whole threads on this forum devoted to explaining what's wrong with it.
But my system can sustain SINAD from source to amp speaker outputs between 85 and 90 dB. (No speakers are that good, period.) If you think that's easy because your DAC has a SINAD of 120 dB, then perhaps you should measure it and see. I have done so.
I totally get the problem of vinyl enthusiasts implying with their nostalgia (and sometimes outright claims) that vinyl is a superior medium for whatever reason. That's silly, of course. But I don't see that on this forum, except from the occasional troll. Given that this is an elsewhere problem and not a here problem, I don't know why we keep being forced to relitigate it, when in general there is no disagreement.
The question of this thread was this: Has vinyl improved in the last 30 years? Answer: No. It's as bad or as good as it was in its heyday. I think that was answered adequately on Page 1.
