(Audio noob here, so please help me out if I've been misinformed or if I'm mistaken about anything)
I've currently got the Xonar DG sound card and a pair of V-Moda Crossfade LP2s that I use for gaming (competitive FPS) along with a Zalman mic, and I'm looking to upgrade. I've been eyeing the Sennheiser HD 598s, which supposedly can be powered just fine by the amp in the DG, but there's one thing holding me back from making the purchase: The HD 598s only cost $200, and I've got a total budget of $300.
So my question is, should I get the 598s and spend the extra $100 on a DAC/amp? If so, which one? What kind? I'm pretty sure that will make my sound card obsolete considering such a thing wouldn't pass through it.
OR, should I buy a different set of headphones entirely; a pair in the $250-$300 range? I hesitate because most headphones in that range require amps, but I've heard that you don't necessarily need an amp, and you should see for yourself whether the headphones in question can be driven by your current setup, even if whatever you're using isn't rated for the impedance of said headset.
I'm thoroughly stumped, and could really use some advice from someone more experienced than I.
