tried the R1900T3 at show room last week. but the speaker cant reach my expectation, or mayb it just need some certain tweak or software tuning to make it sound better. what i heard in the showroom is the sound very messy, no staging and no layer, and the bass are like uncontrol . anyway, i will go back and try again bcoz i really want to get a new speaker. one more thing, the R1600 really surprise me, the sound is so natural, original...very suitable for me actually...haha...and one more thing, thanks to the promoter at edifier showroom, super nice guy, but just he talk too fast...haha...really cant find such a nice promoter anywher else...
