Engadget posted a story that Creative introduced it's new Sound Blaster Z-series

The latest PCI-Express cards use the firm's Core3D quad-core sound and voice processor and come in three variants: the Sound Blaster ZxR, the Zx and the Z. As you might have guessed, the more letters, the higher up the food chain it is. The flagship ZxR ($249.99) boasts a 127dB SNR, sockets for swappable Op-Amps, 80mW into 600 ohm headphone pre-amp, plus RCA / optical connectivity (via additional daughter board) and an external "ACM" control module for less fiddling around the back of your machine.
