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.
Ah yes, @xcool , that does bring back the memories.
We'd get together after work or on the weekends and fire up my Magnavox receiver and put in an 8-Track or put on an LP and the peace pipe would come out. . . . We didn't know what imaging or sound stage or transparency was . . . but we sure had fun. Now my sound is in a completely different league, but I don't have near as much fun.
