OK, i just solved the biggest issue to my lack of enjoyment of using the x2...
i did a test and found that at .3 seconds, the X2 adds an audible fade in to a high frequency percussive transient i was using for testing, but not at .4 seconds. the .3s fade in was subtle, but still clearly audible. i'm guessing that .35 seconds is the actual fade in point, but from now on, i'm adding .4 seconds to every track i import into the X2 for TRUE "seamless", if not gapless, playback.
i went back and added .4s to the start of every track in a folder of BBC big band orchestra tracks and find that listening to music on the X2 has become a lot less stressful, but the nice sounding superlux 681 EVO cans i'm breaking in that don't skimp much on bass are probably helping too. all i know is i'm no longer distracted by the start of EVERY track i've edited for instant starts and seamless playback on gear that doesn't artificially add gaps & fade ins getting cut off and making me clench my fist and teeth.
i should be going to sleep, but i'm finally enjoying my new & improved rig for once.
if fade ins are driving you nuts too, add .4 seconds of silence to the start of every track (or even better yet, mix them into clumps) and no longer be annoyed by your player trying to tell you when it thinks a song should start without asking you.
i never realized just how much those fade ins bothered me until i listened to adjusted tracks in their entirety.
ALL media player manufacturers need to pull their thumbs outta their butts and fix that crap! it should be EASY to do, and if ANYTHING, they should go the other way and overlap tracks for totally gapless playback. i DESPISED my cube 60 for the same reason.
