I have had my Crown(D150a's/DC300a"s) and JBL (L65s/L100s/L300's) since the 70's. Not much I have heard has made it worth me changing. My basement system with the Electrovoice EV-Six's from 1965 with 18" woofers sound damn near as good.I can't wait to hook up some tube amps to them,for now I still love my Crown/JBL combo.....
