Creative has expanded its Sound Blaster (SB) X-Fi Lineup with two new entries. The Titanium series marked Creative's entry into true PCI-Express hardware-accelerated audio. The Titanium series cards are said to have a tweaked CA-20K audio processing core that has native PCI-Express interconnects to the rest of the system. It is also said to run a lot cooler than its older variant featured in some of the PCI versions of Sound Blaster X-Fi. First up, is SB X-Fi Titanium. This vanilla version of the card features the same PCB as the other variants. It is best put as the successor to X-Fi Xtreme Gamer. It has the same audio processor, DAC and OPAMP circuit, just that the X-RAM buffer isn't provided. In its place, a low-capacity memory chip that keeps the CA-20K operational is present. That shouldn't in any way affect its function or quality, except that the X-RAM feature which will be lacking. The card lacks an EMI shield as well. This card has been put on sale for weeks now, on popular etailers such as Newegg. It carries a price tag of around US $100. Next is the card we are interested in, the card is SB X-Fi Titanium Professional Audio. In many respects, the card is close to being identical to the X-Fi Titanium Fatal1ty Professional. The card lacks the Fatal1ty branding, perhaps to give it an audiophile card's look. It bundles 3.5mm to RCA converter cables. The software bundle includes Creative Media Toolbox, a content creation software kit that takes advantage of the card's Audio Creation Mode. Other than that, nothing else advertised seems to differentiate it from the Fatal1ty card. It has been published on Creative's Hong Kong website here, and is priced at approximately US $154.
