Creative USB Sound Blaster X-Fi Surround Sound 5.1

Creative has just followed up with a member for its X-Fi series. Dubbed the SB-XFI-SR51 Sound Blaster X-Fi Surround 5.1, the external USB sound card boasts 5.1 surround sound and Xtreme Fidelity. The company's Xmod also belongs to the same USB category in the X-Fi family except this less costly solution cannot do surround natively and emphasizes on the surround sound virtualization on headphones with CMSS-3D. Both the Xmod and the XFI-SR51 come with 'crystalizer' that supposedly improve sound quality of lossy MP3s.
