Audio Testing
Audio testing provided decent results in RMAA testing, but I did find that multi-streaming was not enabled for the front-panel ports. I consider this an oversight on any board.

In actual usage, the volume provided by this design was more than adequate, and actual audio reproduction was perfectly accurate to my ears.
RMAA results are below. Considering everything, this is one phenomenal result:
