Need the help of someone who knows about DAC and Amps, please... I have a Sennheiser HD650, and to drive it I got the well known Beyerdynamic A200p and, in my computer, a Motherboard which has the following specifications of audio (see the image below). As you can see, it uses Cirrus Logic CS4398 as a DAC and a Texas Instruments LM4562 as an amp... Question is: which one should give me a better sound with the HD650, the A200P or the Motherboard? (yes, Im too noob to hear the difference for myself). Thank you.
