I'd chalk the difference up to two different things:
1) Records were mixed differently
2) Speakers and other audio gear were designed differently
I currently own my father's Realistic receiver, turnable, and speakers (2x10s with a high frequency tweeter as well) which was made in the late 70's. Playing albums like Eliminator, Synchronicity, and various greatest hits records show that there is definitely a difference. I notice a LOT more low-mid punch and presence to a bass track on record than on CDs these days. Most of the time speaker manufacturers for computer audio and car audio go for that really scooped sound so that it comes off sounding really clean and open...but your mids are rather absent (Bose tends to do this with their audio products). You get something that does highs with a smidgen of high-mids and then woofy woofy sub lows from your subwoofer, while your mids just get lost in the mix somehow since they are either muffled or not present at all.
Tone and what sounds good can be debated, but I can make out the basslines on all these old records MUCH better than I can on anything else I've used or listened to before...monitoring headphones included.
