Is this threats talking about all sonic gear speaker or certain model only? I was thinking of going for Sonic Gear A5 or A7. The sound quality from A5 not bad but i'm not sure about the technology itself. Is it as worst as Evo? Or is way more better?

I'm previously using AL VS4121, lots of humming sound came out from the woofer as well as for the latest VS4121 that i tried from Viewnet at lowyat. Is not really good for long term using coz the humming is getting more and more. Even when I switch on my speaker while my fren in the same house is playing game, his computer speaker getting the humming too....mmmm....

Anyway, i just wanna know about SG A5 and A7, is it worth to get it? Rm205 for A5, RM299 for A7....
