At the intersection where cutting-edge audiophile technology meets 30 years of experience in Sound Blaster processing. The Sound Blaster AE-9 is simply the best PCI-E sound card Creative has ever built. It combines great hardware with 129 dB DNR and 32-bit / 384 kHz playback from the high-resolution ESS SABRE reference 9038 DAC. But it's not just about technical specifications. Creative has thoughtfully considered all aspects of the product, including the introduction of a brand-new feature - CleanLine technology, which has been developed from the ground up to eliminate issues with the power rail and isolate noise along the microphone path for crystal-clear voice communication.
