Rage3D published a review of the Auzentech HDA X-Plosion 7.1 DTS Connect soundcard

The X-Plosion is well made, better supported and full featured. It’s only real disadvantage is the lack of support for newer revisions of EAX. However, most games that support EAX4 or even EAX5 also support EAX and EAX2 which is handled by Sensaura emulation. Hopefully, AuzenTech’s efforts to support OpenAL in conjunction with other HD Audio adopters will move the game industry into supporting the open standard audio engine.
