Hey guys planning on getting my wife her own sound card to fit her senn hd 700. (both gaming and just music or video). I have a Asus Xonar Phoebus but she didn't want to have the same stuff as me. There are many other good but which one do you guys think is better? Note: we got a 5-10$ sale so it's better than the original price. (converting price to us dollars) Asus Xonar D2X PCIE Audio Card = 146.92$ Asus Xonar Essence STX PCIe Audio Card = 134.70$ Asus Xonar Essence ST PCI Audio Card = 159.19$ or just grab the same as mine? Asus Xonar Phoebus PCI Audio Card = 171.41$ just wondering there is a big difference in price between the stx and st but looks the same? when using google they said it's the same and looking at their specs the only difference is the stx using pci and st using the pcie. will it produce a ground breaking sound better than the stx? how about my phob? it's using a pci slot comparing it to the st with it's pcie? her speaker if I recall correctly is a 5.1 or 7.1 if it means anything (uses it when watching movies or youtube and stuff.) clarified it's 7.1 hehehehe note2: she likes asus brand so other brands are a no go (besides that red headset/phone from asus that she said looked ugly).
