the ACS45.1 is real good stuff despite lacking in treble

but for now.... I doubt you can find anything as worth paying as ACS45.1 as compared to the standard Edifier now

I don't really know how to choose for you because... they are both different stuff and they both excel in different section.

if you want classical quality looks then the Edifier can give you the luxurious wood
if you want casual but powerful surprise in looks the plastic enclosure of Corsair is very fun to sit on your desk

the only way I can separate them is by looks because both are totally different beasts that I both love.

if you are going to pair with tv use then S530D is the only good one because of the extra wireless remote and That's All
