I haven't been listening to my AD900X in a while but I will try them out with the player. Let you know when I get a chance tomorrow. I am thinking the sound signature of the X3 will do better for the AD900X over the DX50.
The bass end of the X3 is more emphasized over the DX50 so this should help the AD900X even more so..
On another note you've got me very excited for those over-ears by Philips that are coming out. $300 is a decent price tag, but after reading that review I'm definitely tempted.
My $0.02, just sayin....
