I use a SoundBlaster X-Fi GO USB dongle for my audio, which is now getting extremely old and is having occasional problems. The X-Fi crystallizer is the only feature I'm actually interested in, especially as I only have a stereo speaker setup. Am I right in assuming the 24 bit crystallizer is still present in all Creative's newer cards? Do their rivals have an equivalent feature? Can onboard sound / low budget cards even have something like it? I once read that the USB X-Fi dongles actually don't really have any hardware, it's essentially just running software and using your CPU to increase audio fidelity - can anyone confirm this? Is there even a way just to have a crystallizer as an app or something and use onboard audio?
