Congrats on the custom M50's!
When visiting Axiom the first time, I was able to play with the M50 vs M80 on a switch box. Oh yeah also EP500 and EP600
I originally planned on getting the M50 and thought they were fantastic and was amazed at the bass they through out. I ended up splitting the difference and buying M60's as I wanted a little extra clarity and mid punch. While processing the order with Noreen, my buddy was in the demo room with a couple Axiom folks and the room started to rock. I told Noreen I would be back in a second and high tailed it to the room. Upon opening the door and seeing my buds goofy grin I sat down to join him. After the song was over I asked what were we listening to?? M50's in stereo...couldn't believe how good they sounded and how much bass they provided on there own...enjoy yours when they come.
