Pros: great neutral sound, easy installation
Cons: not the cheapest, needs a good power source
I wanted to upgrade my computer sound card in preparation for higher impedance phones and eventually a desktop amp. This more than does the trick and improved onboard sound more than I'd expected.
The con about it needing a good power source isn't an argument against it. It turned out that my computer (Vostro 420, 2009) didn't have an extra power connection for the card so I ended up upgrading my power source as well.
