I actually think the SM3 and the XBA-40 are the most natural sounding BA IEM's I've ever heard. It's probably due to the fact that they are also much darker than most.
It's amusing being a Chinese person in China who can't speak Chinese. (or at least in Shanghai). Everyone was just bemused.
Arrgh get better soon!
Also I hope your body does not become a natural incubator for some bioweapon level super virus.
Would you also consider the prat on them slower as well? (than say a BA with fast prat). :)
