Just got UE900's myself while they were half price. I find them technically, a far better sound than the TF10 in every respect, but I hate the mmcx connectors and the memory wire is not very good either. I also find their more neutral tone, not the exciting sound that the TF10 is.
My UE900 are either going to be reshelled and maybe an extra driver added, or sold. Not sure which yet.
Reshells may not be as expensive as you think. Check Cosmic Ears website, they are in Sweden so you won't be stung for any import duties in Italy. They reshelled my TF10's for me and did a great job.
