Ok, so I got a pair of Sennheiser HD 598s, I mainly use them on my desktop that has onboard audio (ALC892). And I have 100$ to spend, maybe a little more even, if it's worth it, I'd go up to 200$ max.
At first I was convinced I wanted a Fiio E7/E11
But then some people told me it would be better if I got a new soundcard.
Then a user on here suggested I get a Xonar DG and a Fiio E7/E11.
Is the Xonar DG worth it? It's pretty cheap, so will it make a difference over the ALC892?
Also, will it stack with the Fiio E7? Or will both amps cancel each other out? I'm just so confused, and I'm open to ALL suggestions, please help me get the best out of my headpones.
I also use them on my iPhone sometimes.










It would be nicer if you could A/B, but a hassle, so far yes it is an improvement, but unfortunately when i switched to the speakers i only get sound out of my left speaker. You probably have to restart the computer each time you switch output.
