Seriously though to answer your question...Based on your Classical music tastes I think you should consider some Martin Logan electrostatic speakers like the Classic ESL 9 , or Impression series, your Mac equipment will drive them no problem. Also, Dynaudio speakers would be amazing with high powered amps like the MC452. Good luck, I'm excited for you!
