Have been burning the Pistons for about a day, I'll try some Complys and connect them to my X3/National set up and have a listen in a bit, when I get to bed (get some of my best listening in then, that's why I use my iem's more than the on or over ears, though I am liking the on/over ear presentation more and more.
On a different note-X3 is fabulous sounding, though I haven't gotten the UI down. Can use it in the file explorer mode, no problem, but the other ways to search, Artist/Album, don't work, I get errors opening the same exact folders/albums that work fine in the File Explorer Mode. Have been lazy about doing anything about this (or, the positive spin, as my wife the therapist would say, is that I've been too busy: I like that better), as I can find and listen to anything easily with the File Explorer mode...the only thing I lose is the Shuffle/Random play option, for which I still have an iPod Touch, and I pull that out in situations when shuffle is the way to go,
