wot really many people using edifier.. was it really good? i not sure cause never use before.

currently i using a very old modal altec speaker ADA885. was it better sound quality in 4.1 or 2.1 mode? using philips aulirium soundcard wit windows vista 64bit. ( unlucky cause no driver avaliable) so use plug and play only.
can any people gave some opinion how to make the best setup for me?
i will post the pic tomorrow.
