Never got a chance to test Aego M but played with T3 couple of times. Its a nice speaker for gaming and movies coz its crisp satellites and heavy bass. But hey, its also sounds great playing music. Just tune down the bass so the vocal and other instuments not covered by its bass 
Go for 5.1 surround speaker like Edifier R501, blasting it will give more pleasure in surround sound environment. Like when you playing games or watching movies, the bass mostly will rumble you body and it will make you feel amazed. About Kave, since its a headphone.. you'll get an occurate and clearer sounding since the driver just deside your ears  . But wearing a kave for long period of time will cause you a pain since this headphone are quite heavy. Your call 

u can get the Edifier @ PC City.

You like bassy speakers? try Logitech X-230 
Go for Edifier P3060 or Edifier M3300. Go audit it 1st before buy
