Stinkysbsc you won't be able to try a ba200 at jaben. Stereo has it though. I bought it from em at s$158. I've never tried the sm3s before but I can tell you that the ba200 is quite smooth at the top and th soundstage is quite good...plenty of width and airy too. But the bass is not as fast and punch as I'd like it to be although the quantity is impressive.
Is it the one on Orchard Road? Also, what is the store like for auditioning? And what store is your favourite in singapore?
