depends on people actually

a kampung guy perceive ppl who drive honda city is freaking rich
a city guy perceive him as average.

same thing, most people here who comment have not experienced all the three brands you stated before, and their prejudgements are solely based on reviews and words of mouth.

and of course we know sonic gear makes rubbish speakers(just crack open the speaker and see how terrible the building quality is).. sonic gear speakers are eye-catchy towards those who likes bling bling lala lights etc etc..

altec lancing used to be on par with logitech like 5-10 years ago. but they're bought by plantronics and quality seem to drop slowly :/ but i think their high end range are not bad though?

among the three edifier probably takes the top spot.. good build quality, less boomy but strong bass and clear sound.

its all depends on human taste though. If your happy with a Rm50 speakers then stick to it.
