Pros Drivers are easy to download and upgrade, cute helo simulation
Cons Cracking and distortion, sounds are left to be desired
Summary Don't waste your money. My first Diamond will be my last. I have Accoustic Authority 2 speakers + this huge subwoofer. Never, ever did it give me problems. My speakers produces louder volumes with really good clear music which sounds better than Logitech and others (not just my opinion). I moved them from my work PC (yeah, that is right- from a Navy ship that used a Dell PC with onboard sound) to a HP with onboard sound at home. Basically put, the Dell was better with onboard sound. Knowing my speakers are better, I upgraded to Diamond and downloaded all drivers from CD-Rom/website and the result was just terrible sound with distoration, crackling, and even when that didn't happen, the overall sound was worse than my onboard sound. You guessed it- returned it. I would have gave this sound card a 3 (poor rating), however, I give them a 4 as it was pretty easy going with the drivers.
Pros Coaxial digital output/inputs
Cons Included drivers didn't work with Windows Vista
Summary I was looking for a better way to connect my PC to my home stereo. I was using the 1/8" mini-plug on the factory sound card and split it into a pair of analog rca cables to my A/V Reciever.
It worked, but the problem with running analog cables that long is that they're prone to ground loop hum, which I did have at high volume, My answer was a digital coaxial or optical cable.
The Diamond Xtreme box describes the digital coaxial outputs as S/PDIFs. I wasn't positive this was what I needed, and the kid at Staples had no clue either.
The hardware install was simple enough, even for a first-timer like myself. But it turns out the included drivers aren't Vista compatable. Luckly, Windows offered to search the net for updated drivers and easily found and installed them.
Problem is, there are a few features such as mixers, graphic equalizers, etc. that were supposed to install but were not. This was not a problem for me, I wasn't really interested these extra features anyways, but someone else may feel differently.
With a custom 28' digital coaxial cable from "Blue Jeans Cables .com" ($33 delivered), the soundcard works great, and did just what I wanted it to do.
