Don't have XBA-3 - otherwise, BA200 is the best sounding of them all. I'll place UE700 on par / around the same level with MH1 and EPH-100, but UE700 will be more neutral that either. It is still warm sound however.
I am not sure when I will write it, but I'll write it for sure. It just that I have too many review needed to be finished and I am very busy with life outside of HF.
