Hi, I recently bought a DVD player(samsung DVD-P475 Model which supports 5.1 channel audio,has digital,coaxial and analog support). I am also planning to buy 5.1 channel PC speaker(Artis S6600 which has seperate amplifier/Logitech x-530 model).when I said about this to computer service engineer,he said that we need to use a seperate converter to go for this combination. I visited logitech site and they have mentioned that we can connect the speaker to PC,CD,DVD,Playstation,Xbox etc.. (http://www.logitech.com/index.cfm/products/details/GB/EN,CRID=2177,CONTENTID=9067) Artis has a independent amplifier(http://www.artis.co.in/s-6600r.html) Has anyone tried this combination?.If yes tell me how to do the same.Also tell me what all things we should keep in mind to arrange this setup and tell me the purpose of DTS amplifier,Analog amplifier with their difference Guhan
