I recently bought the PC37X from massdrop for gaming- my first open back headphones and loved the difference compared to closed earphones. So I ordered some HD6XX for music. I now need an AMP/DAC, and to be honest as a complete NOOB it's a hard task sifting through previous information and defining a clear choice and having any understanding why it may be better than the other options out there. The Aune X1S is on massdrop at present as is a DarkVoice 336 tube amp, alternatively i have been looking at the JDS element or the schiit Magni 3 & Modi 2. The element is probably top end of my budget at $350, but probably more than i want to pay given the headphones are $199. So what do you recommend, and what offers the best bang for the buck?
