I love having a 10-band equalizer. This is the only amateur, sound card/ game card with a real-time full-bandwidth equalizer. Most of the new home-studio mixer cards can run circles around it, but they are in the $500 range, not the $100 range. This one had a good positioning. I just hope the company can keep improving the software (actually the UI software is made by Voyetra, a major player in home studio software).
Like any card, it can be a major hassle to set up in your particular system. And it produces an audible level of digital background noise. There is enough headroom so that this noise can be fixed by boosting the preamp signals to just before distortion (thus running at the full 0 db level), then doing overall cut via Radio Shack inline "headphone volume control" (42-2459).
Core Dynamics is the company that makes the DynaSonix Pro. Sound Blaster is really making life hard for the other companies even when the other companies innovate. Core Dynamics was one of the first to put a DSP chip onto a "sound card" or "game card".
