no...no...there's a different between em both...mine, euro version, the soundsig are rubbish...:o and the nano of my pal, the US version, have SQ/soundsig much more hi-end than mine...i can feel the staging ARE exist there, mid & bass detail have more impact, so agressive...more brighter than mine, almost had the same sig as ipod video...my nano are too 2D, bass rolloff, hi & mid detail are meh...the whole soundsig are warm, different from the US version...
that's why i need to know HOW to change the version, please...
