Upgrade from Aego 2 -> I went Creative Gigaworks T3

T3 focused for music.. Very detailed..

MX5021 good for movies and games..

I would say go for the T3 if u have the cash to spare.. 

I'm not saying the Edifier S730 isn't good. It is. But ask yourself this, why would excellent audiophile grade speakers provide separate bass & treble controls?

I have heard the MX5021 before, but not in direct comparison to the T3 or the S330/S2.1M.
I do admit the MX5021 sounds good, but fails to deliver as a audiophile speaker. It's more suited as a general PC replacement speaker. The bass while impressive, isn't tight. It feels a little missing in delivering a forward midrange. Treble while present, isn't focused, and at times, sound overly too bright.
It does not come close to the T3 in overall music quality. In fact, the Edifier S330 fares much better musically than the MX5021. For that kind of money, I'd buy the Edifiers anytime for RM295. Save the extra $$$ over the MX5021 & upgrade your sound card.
As you are aware, the MX5021 has poor signal-to-noise ratio approx S/N of 80db. You can almost certainly hear the "hiss" when nothing is playing & in quiet surroundings.
The T3s exhibit excellent S/N. You cannot hear any form of hiss even when you place your ear next to the driver & in quiet surroundings
At the end, have a listen before making your decision.

i doubt two person buy will get a lot of discount... still unaffordable currently cos i really dont have much cash with me right now.. unless can reduce to rm150, then i can buy now la.. hehe. but hey, good luck if u wanna buy one! glad we have the same interest!
