I am looking to upgrade to the Xonar Essence STX with 3x LME49860 Opamps. I am currently running the Xonar DX paired to the Sennheiser HD598's.
My question is; Anyone with experience with both, know about how much improvement I should expect? Or then again is it even worth the upgrade cost? I am looking to get the most from these headphones that I've spent 250$ on based on everyone raving about them and how good the sound stage is. I am not getting the sound stage I expected to get and thought perhaps a better sound card would be in order.
I mainly listen to Music with some Gaming. I have purchased the FiiO E11 Amp, since the Xonar DX has no built in amp and at 100% system volume it was too weak for me.
