hey for any of you guys that own a x-52, if you dont like the sloppiness of it, go and pick up a plastic CD holder, (the shorter one its about 4 inches tall)
you can see a small round indent in center, cut out that center and then cut out the smaller center,
pull down the spring of your x-52 slide in this plastic "washer", works awesome for tightening it up just enough, i tried metal washers but they just dont work very good. this is a perfect cheap fix.
