The subtle clue is in the name – the X means this is the PCI-Express x1 version of the Xonar D2 soundcard that we reviewed in September of last year. Since then the promised PCI-Express x1 version has finally arrived, along with better DirectSound, EAX and Vista support via updated drivers.
Comparatively, there’s very little change in terms of the style and feature sets available on the D2 and D2X – they both have the same EMI shield and illuminated parts, and apart from the change of interface the only other notable thing is that now the card requires an additional power source. Yes, PCI-Express x1 may be an improved interface but it apparently provides the wrong type of power.
