I recently upgraded from the Sennheiser HD 598 to the HD 650 and was wondering what people's recommendations for DAC + headphone amps are for the HD 650s. I'm using it for home use only and was looking to spend $200 - $400 range. I heard that the Fiio E09K + E11/E17 was good but wondering if...

Hmm thanks. I guess another question I would have is would a $200 DAC perform better than a $200 sound card? I'm up for any other DACs or any other sound cards if anyone has recommendations in the $100 - $200ish price range.  

Hi, I recently bought a Sennheiser HD 650 and need something to drive them with. Would getting the Asus Xonar Essence ST have a better sound quality over the Fiio E10? I'm willing to spend up to $200ish for a Dac or sound card. I'll be using it for mostly music. Thanks
