I have been contemplating getting one of those samsung or w/e 5.1 surround sound systems. I am currently using these older 2.1 altec lansing ada305s and they sound good but I was curious about how the digital stuff sounds compared to basic type speakers? I am also wondering what is the best system in the lower $200 range? I know a forbidden place for electronic shopping that has a samsung 5.1 that is $199 ready to go.. should i stay away from walmart shit? what should I look for? which specs? My sound card is Xf- and does 96khz.. would I be using an optical cable preferably? Last question... I think my speakers currently sound decent.. lotta bass, and its crisp.. but i am sure it lacks some range but I wouldn't know because Ive never owned digital stuff. So, with games like BC2 that have Dolby digital, what does that mean exactly? If I had a digital sound system would I think it was totally worth the $200 even though my speakers don't sound all that bad? id appreciate opinions from anyone that owns digital gear that went from basics and all help will be thanked. someone on the list is selling logitech z5500 set but the controller thing doesnt work.. @$140? I dont care about the controller but i hear this system is good?
