Summary: Purchased for HTPC. Using 5.1 analog output. Software setting for bass redirection, crystalizer, and EQ all work wonderfully. The software also does a good job converting 2 channel audio such as music into 5.1. I have not used the digital output in any way shape or form so can't really comment. For the price, you can't beat it.
Pros: Clear sound, good software/drivers, as advertised
Cons: No bass boost option on analog outputs 5.1 other than a check box so no true bass level adjustment when using analog outputs.
Pros: Much cleaner sound than the Recon3D that I had. I also upgraded from the X-Fi Titanium and must say that Creative has got this one right. I can only imagine how the Zx and ZxR sounds. The sound is much warmer and accurate. As far as games, positional audio is 360 degrees, which is what it should be. Good job Creative.
