I completely agree with this review. Excellent analysis!
I was just thinking to myself while listening to the X1s that I have finally found a headphone that not only gives me that fun, warm sound all while retrieving excellent detail and imaging in a large soundstage. It's a feat that I personally haven't seen done this well until I heard the X1s. The X1s are seriously making me reconsider my entire headphone library right now, which include the T1s, Signature Pros, MA-900s, HP100s and HM5s.
I'm not saying the X1s are better than all of those but it all comes down to which headphones I reach for. Since getting the X1s they are the only ones I am listening to. They handle music superbly and when gaming, I get all of the satisfying bass and explosion sounds all while still being able to pin-point and image with great precision.
I am seriously very impressed with these cans.
