At the intersection where today's cutting-edge audiophile technology meets 30 years of Sound Blaster processing experience, we set out to redefine the best of PC audio. Paying homage to our audio enhancement legacy and our never-waning thirst to explore the possibilities of audio, the Sound Blaster AE-9 is quite simply the best PCI-e sound card we have ever made. Marrying the best of hardware with a 129 dB DNR and 32-bit / 384 kHz playback from the hi-res ESS SABRE-class reference DAC and our very own Xamp fully Discrete Headphone Bi-amplifier, together with our critically-acclaimed Sound Blaster audio processing technology that has been refined and perfected over the last 3 decades, the AE-9 can be described with a single word - pristine. The AE-9's CleanLine technology features a specially designed circuitry and components that eliminates voltage rail issues and isolates noise along the microphone path that typically plagues internal audio cards. We utilize a differential drive for the mic signal to reduce the common mode noise that may be induced by other electronic sources. The Sound Blaster AE-9 works with all kinds of headphones, driving audiophile-grade headphones up to 600?, all the way to sensitive in-ear monitors with its ultra-low 1? headphone output impedance.
