I'm a complete noob in DAC's, so I have to ask, if either are actually good?

Thanks for the reply   I'm also looking into USB DAC's, or getting something like a Xonar DX used would be an option aswell, or something like Creative SoundBlaster Z, if those are any good at all. Any recommendations?

Hey guys, I already posted this once, but in the wrong sub-forum.   So, I'm able to get the Beyerdynamic MMX 300 headset for about 60 euros (80$), I'm wondering whether I should go for it.  Also, would they be a sufficient upgrade in terms of general audio quality over my Superlux HD681...

Alright, thanks for the reply. I just found it quite amusing, finding these for 85$, when they retail for over 300$.

Hey guys, i'm new, so if this goes in the wrong section or something like that, let me apologize :)   So, I am able to get a slightly used Beyerdynamic MMX 300 Headset for about 85$, should I go for it? I have read some good things about this headset, but still not sure if that's a good deal...
