Plus, Im not sure if the crappy bass, for which I returned the card was due to the cards amp or the DAC. I think it was the DAC, so I am a bit sceptical about buying it again.
Would I really benefit from upgrading to a DX / e11 in comparison to my e17?
As an alternative to slickmans suggestion I came up with a topping tp30, since I can order that one via amazon and spare duties etc.
The Fiio E17 seems to be a great portable DAC/Amp, but is only 2-channel (stereo) audio, so on it's own can not convert 5.1 or 7.1 audio to surround sound for headphone use.
You will get great 2-channel stereo sound for movies (and music) with the E17.
The Xonar DX does not come with a headphone amplifier, it comes with a line-out jack that pretends to be a headphone jack.
The Xonar DX will have less then good bass for just about any headphone used plugged straight into it.
I'm very sure it was not a "DAC" problem, it's an amplifier problem.
It also might have been a software problem with the Xonar DX, get the "Unified Xonar Drivers" from the Brainbit website.
The Xonar DX can convert 5.1 (6-channels) movie audio into Dolby headphone surround sound before sending out the "line-out" jack, to whatever headphone amplifier you have connected to the Xonar DX.
I know little about the Topping TP30, like what is it's headphone output impedance?
I would say to try and find a used O2 (Objective 2) headphone amp. I know it has a very low impedance.
