Shauup, IMO it's not all the detail, it's that some systems have tipped up treble that passes for detail. Also, many high end systems have completely eliminated bass since it's problematic and expensive to reproduce well. 70s rock without adequate bass is boring. Hyper treble isn't fun to listen to even with good recordings.
BTW, I don't know how you can stand to listen to that old rock. I agree that much of that music was brilliant and unsurpassed by future rock artists, but it's been so overplayed that I can't listen to it at all anymore. The internet has made it possible to find lots of new modern recordings that are extremely good and I'm not talking about smooth jazz. Rock, pop, folk and alt country that is extremely good. I highly recommend searching out new music. It's well worth it.
