Gigaworks T3, Edifier S530D, Corsair SP2500 and Harman Kardon Sound Stick III

nothing beats the awesomeness of Aego M in vocals

I can say both Edifier S530D and Corsair SP2500 have very good vocals

the Corsair SP2500 vocals will sound more cold while the Edifier S530D gives a warm sound.
not much I can give about the Harman Kardon Soundsticks III and Creative T3 because to me both subwoofers tend to mess up the vocals quite a bit.
How about trying some new Edifier Studio line?

like the Edifier R2700

I believe that will have better FULL BODIED vocals like how I like it. (haven't test them though but my assumptions are close to accurate since I believe larger speakers create more full bodied vocals than puny 3.5 inches midrange)

T3 is great because Creative is well known among normal market

T3 is great because it suits various modern genres without limitation (however because it can do all.... there is no certain special skill in it)

Aego M isn't that great because it limits to only people who researched deeply or people who are audio fanatic

Aego M is not that good because it doesn't play well on various modern genres... however it shines miraculously on slow peaceful songs (now that's Aego M's special skill)
both has their ups and downs so... it's up to your ears in the end
hope some of my words help
