for me, GMX tweeter not bland well with the mid driver. feel like im listening to separate unit of mid and tweeter. even edifier s2.1d have better satt than GMX. 
*from my judgement*

GMX may not describe as bright coz the bass already cover up its bright side.

relax man. i have to admit mx5021 sound bright. but that doesnt mean gmx sound better. our setup are different so cannot compare both. and i only listen to mp3 and some flac, not those well recorded original cds.

im using mx5021 coz i like its sound. not meant that im the fan boy, since i tried both before i bought it. my point is i liked, i bought, and tell others about what i feel.

sorry for all GMX users or fans. i think both are good buy for their price. not much to expect for RM500 . i think GMX better for thread starter since he like movies and gaming

a quick search of your previous posts revealed a recent [and lenghty] post on the gmx, the mx5021 and the aegoM

the one comparison againts the mx5021 i did read was personal preference on 'overall sound signature' which of course is a subjective thing and your preference would most probably vary greatly to the next guy.

cheers.
