UE900's are pretty nice. I had the old version for months without any issues. I did prefer the W4R over them but nothing wrong with loving the UE900. Why not try the Luker version of 2.1? You can always revert back to the ibasso 2.1 or even 2.0 if you feel like you're missing something. The UI response alone and the snappier start up makes it worth it assuming sound stays relatively on par.
