i have a laptop ... so getting a PCI card is out of the question.. I currently have hte Lite AM-Dac which has for inputs coaxial, optical (toslink), Aes this dac runs to a WooAudio6 with upgraded tubes through RCA outputs (the woo audio is not balanced.. the dac is)... in any event im trying to find the BEST way to go from my computer to my dac... (only the three inputs mentioned above.).. It would obviously have to be something USB or expresscard... but im not sure.. I was told that it doesnt really make a difference and i bought this.,.. http://www.newegg.com/Product/Product.aspx?Item=N82E16829270009 i would only be using hte optical part of that.. so it would not be movin the signal around? or do i want to go for another direction... whats my best option..
