MSI Big Bang XPower Review: X58, Military Style
Onboard Audio: QuantumWave Weighs In

We don't normally spend much time on motherboard audio, but MSI has put a fair push behind its QuantumWave Audio. The XPower's advertising claims that QuantumWave's support for THX TruStudio PC and EAX 5 (licensed from Creative) gives it the "most powerful and realistic gaming audio performance available from any motherboard."
The actual chip behind all the lights and magic is a thoroughly pedestrian Realtek ALC889. Not that there's anything wrong with that, but one normally doesn't think of Realtek when envisioning awesome audio solutions. Has MSI's special software sauce sparked sensational sounds?
Let's have a look. We tested the EVGA's Realtek ALC889 chip against the MSI board's and tossed in a Creative X-Fi ($49.99 at NewEgg) for comparison. Testing was conducted by looping an audio cable from the speaker output to the line-in jack in all three cases. Prior to testing, audio levels were adjusted to produce the cleanest test signal possible.
We tested sound quality at both 44KHz / 16-bit and 96KHz / 24-bit. RMAA runs a variety of tests, ranking each test on a scale of 1-6, where 1 = Very Poor and 6 = Excellent. The test than gives a "General Performance" statistic, which we've reproduced here.
All software-side adjustments and dB tweaks were disabled.
