RightMark Audio Analyzer - Loopback - 24-bit/48kHz
My Nine Inch Nails With Teeth dual disc's DVD-Audio tracks are 24-bit/48kHz, and we ran RMAA at that bitrate and resolution.

The ADI integrated audio starts to falter when we dip into higher bitrates and resolutions, but the X-Meridian matches the X-Fi across the board. The Inferno doesn't fare quite as well, falling off the pace in the dynamic range and distortion tests. Surprisingly, the Sondigo card trails the ADI 1988A in the total harmonic distortion test.
