hi all especially edifier,

i have put my interest to buy either M3300 or M3300SF.. my question is, which 1 is more better?? coz after i googled about d specs, both are having same specs, except d design only.. i also did googled around lowyat plaza to test- my- ear on both model, both models are sooo terriffic in terms of sound produce.. & last week i went to edifier booth at PC FAIR KLCC, 1 of d promoters said that M3300SF sound is much more better in terms of clarity.. is it true?? previously i'm using altec lansing v4121, then after use it around 1 1/2 year, i sold it coz i'm not very satisfied with the bass sound produce, having distortion when u put a lot of bass sound on it.. then right now i plan to buy new speaker, dunno whether to choose M3300 or M3300SF.. haiizzz...   

can anyone of u give suggestion?? also, if i buy either M3300 or M3300SF, is there any problems from both models? i.e. buzzing sound, left satellite speaker not working, wired remote control died, etc?? & if all these problems came from old manufacturing production, may i know or is there any code that i can verify whether the speaer i wll buy is new manufacturing production or the old 1??

p/s: this is for my guidance to buy edifier speaker, at d same time will join this club!!!..
