Armando, Perhaps it is in fact true that things are achangin'. Even Nelson Pass may be agreeing with all concerned: Pass labs is in the process of redesigning its entire X series, to be now called the X.5. An X600.5 should arrive hopefully in the first part of next year. Do not abandon the idea of X600 yet. But you may want to wait and have a listen to the X600.5 before you make any final decisions. I know I will.
