50 hours on Monitor Gold 200's enough?

I had 2 sets of identical Monitor Audio Golds. 1 set I used daily for over a year and the 2nd set was fresh out of the carton. Side-by-side, myself nor anyone in the room with me could tell a difference in performance between the two sets.  Just my experience. 

listen to music rather than your speakers.   You're not evaluating you're enjoying.  

All good thoughts. They are good sounding but not getting to the level

I want so the trial is over. Thanks for your inputs!
