Hi, I'm going to build a fanless HTPC for music listening, and this means that I need to get an external DAC (the case I choosed is too small to insert a sound card). Now I have an Asus Xonar D2X, paired with Sennheiser HD650 and a Fiio E9 amp. I noticed that Cambridge Audio DacMagic is...

Hi! Can someone please tell me if there is a difference in audio quality between this two cards. Which one sounds better ? I don't need the 7.1 output of the 7.1 HiFi, 2.0 is enough (I have a pair of M-Audio AV 30 speakers). Thanks in advance.
