I really love the 58X, I am really starting to appreciate it a lot more now that I've been listening to it a lot lately. I definitely like it more than my 6XX, it has the perfect balance of treble, mids and bass for me on a finely tuned Sound Blaster GC7. It is a pleasure to listen to and fixes up all the things that I do not like about the 6XX which was mainly the relaxed nature of that headphone.
