Why Does My Current Music Sound So Much Better than It Did in the 80’s?

I’ve got to ask…maybe someone here knows…is my current system more realistic sounding than what I used to listen to in the 80’s? I’m just impressed by the sound I have now, I just don’t remember it sounding in the 80’s so real, present and full range.

Then I had a Marantz 2245, JBL L166 tower speakers, usually vinyl on a Dual turntable with a Shure V15 Type 2 or 3.  This was decent stuff at that time.

Now I listen to internet radio on my iPad, usually radio.garden jazz, through an Apple AirPort Express router, to B&O BeoLab8000 speakers, a Hsu ULS 15 Mk II and a Paradigm Series 7 12in Monitor sub.  I set up In a big 20ft by 40ft room now with lots of hard surfaces.  I’ve invested very little in this system, yet I’m amazed at the sound.

it’s unlikely that my ears are better…anyone care to rake a stab at why things sound so better to me now?  It would be interesting to understand the evolution of sound.
