Sapphire Pure Black X58 Motherboard Review

Rightmark Audio Analyzer

The RightMark Audio Analyzer suite is designed for testing quality of analog and digital paths of any audio devices, be it a sound card, an MP3 player, a consumer CD/DVD player or an acoustic set. The results are obtained by playing and recording test signals passed through the tested audio path by means of frequency analysis algorithms. The latest version of RightMark Audio Analyzer can be found here.

There is very little performance difference between any of the boards we have tested. Stereo Crosstalk is the only area where we are seeing much of a variance. Stereo Crosstalk happens when one channel leaks to the other; this happens at a certain number of decibels. The higher the decibel rating the louder the audio will be before the Stereo Crosstalk will begin to happen. We are also seeing some variances in the Noise Level and the Dynamic Range, dB. Overall though, I haven’t heard any discernible differences when working with any of the boards. My gaming experience has been a pleasure on all of the boards to date!
