Im sure this has been asked before so here I go on with my question. I have a imac with external creative speakers with a head phone jack. When I listen with my cans Grado SR80's I get detail that my Parasound JC2 A21 Cyrus 8SE with PSX (cardas cables throughout) misses? So how can a $100 pair of desk top and 100 head phones beat up on a $18000 system for detail.
