In interpreting the results on both boards, we see that the Dynamic Range and Noise Level on the ECS PN1 SLI2 is
superior to the Foxconn 975X7AB as the greater the dBA the better. We can also see that when it comes to the THD and IMD percentages, the Foxconn comes out looking much better
since lower percentages mean better audio. Either boards audio will probably be fine for most people, even for gaming and movies. But if you are a die hard audiophile, you will likely get an add-on card for the best sound that is available.
