Hardware Asylum checked out the Creative Sound Blaster X7 and E-MU XM7 Speaker
A quote from the article:
With motherboard manufacturers moving more and more features onboard it is becoming harder to justify add on sound cards. Creative is no exception and has been offering their award winning sound processing out to manufacturers as a high quality alternative. But, for those of you still looking for something more, Creative has the Sound Blaster X7.Creative Sound Blaster X7 and E-MU XM7 Speaker Review @ Hardware Asylum
The Creative X7 is definitely more than just a sound card. Creative bills the X7 as an ultra-High Resolution Audio (HRA) device that acts as an external USB DAC and a powerful audio amplifier with low-latency Bluetooth connectivity and Dolby Digital decoder. And for not much more you can bundle the X7 with a set of Creatives E-MU XM7 Speakers that are specifically designed to match.
