All I can say is time has changed. Back in the 70's, going to friends' houses to listen to their sound systems and album collections was a pretty common social event. These days everyone has access to music in his/her pocket via a wireless headphone. @ghdprentice said it right, audiophilia is very much a solitary pursuit.
These days when I have friends over, I just put on some easy listening music like Diana Krall or Norah Jones playing at very low volume in the background. I never want to draw anyone's attention to my sound system. Music sharing is done very differently now.
Congrats OP on your system. I've never heard of Perlisten speakers, but they sure look cool!
