totally a non-issue as almost all of my files are WAVs ripped from CDs or from streaming audio/videos using audiograbber.
i got my x2 a few days ago and after checking online, went to best buy to get one of the $12 kensingtons they listed on their website only to find they only had $20 and up sandisks so yesterday i hopped on a bus to walmart because their website said they had $10 samsungs which they didn't, but i did get a $13 sandisk. after struggling to get it to click, i finally got it locked in using my thumbnail and it took the very first file i dragged into it without issue and let me create a folder i dragged woofer cooker

the only problem i had was that i juggled an extrenal hard drive and a thumb drive to front and back USB ports so i could free up a top port and windows literally lost its freakin' mind and didn't recognize ANY of the drives anymore! that's not xduoos fault though. after unplugging it, windows found the other 2 drives and accepted the xuduoo once i plugged it back in. i'm guessing it wanted to name the SD with the same letter already given to one of the externals and got confused.
once i had it loaded, i was NOT impressed with the bright and spitty sound, so i decided to loop woofer cooker to break it in. i guess all of the continous infrasonic bass was too much for it as the battery went dead after just 3-4 hours at max volume. i plugged it back in to recharge a bit while i surfed the net then looped a regular dance track for another 5 hours or so. the battery was showing a 75% charge and the sound was MUCH MUCH better! the highs were relaxed, but have gobs of detail. i've never heard my presonus cans sound so good on 3 different PC's soundcards or my sony portable CD player and the bass really opened up too. it's the first time i can actually hear the infrasonics in woofer cooker, if only a little as cone flapping. it blows lightweight clinical sounding sansa clips out of the water with better bass, effortless highs and plenty of volume.
if the competition with a cube 60 with it's class A amp is close, the x2 still destroys that by not blasting ever track a fraction of a second then cutting its volume no matter what volume you're listening at. it also beats my original cowon which was pretty uncolored, but lacked bass wallop or the ability to really crank, and as i said, sansa just doesn't have the balls or treble ease either. the x2 is one sweet sounding piece of gear.
as to the alleged "stiff buttons" issue someone mentioned somewhere. they feel just right to me. the pressure isn't unreasonable and is precisely what i imagined it to be. any softer, and you could get accidental button pushes in your pocket.
for now, everything's working as it should, i love the aluminum casing and cool buttons. i never needed to read the manual. navigation is intuitive, but most of all, this puppy cranks effortlessly and has a nice warm bass that will help a lot of lightweight headphones and really please bassheads with bass cans. as long as reliability issues don't become a problem, i like this player more than any other i've owned by far and it really does live up to the hifi claims. if it lasted 10 years, i could live with it happily and not feel the need to upgrade.
thanks to everyone that helped me find it
UPDATE:
ugh now that i'm listening to it for fun, i've found that the x2 does something unforgivable... it cuts the very beginning of every song off and fades in obscuring drum hits! What is up with chinese players screwing up the beginning of songs?!!! it's cube 60 syndrome all over again! anyone else know what's causing this and how to fix it? i just can't abide by a player wrecking the beginning of a song. despite the inferior sound, that's why i switched back to my clip+ because of cube 60's intro fade downs... now with the x2, it's unwanted fade ins.
ARRRRRRRRRRRRRRRRRRRRRRRRRRGHHHHHH!
