4. Xonar D2/D2X RMAA Testing Results

The following tables copied from RMAA disclosed the complete test data results for

DirectSound_16bit, DirectSound_24bit, MME_16bit, and MME_24bit. Each table contains

44.1K, 48K, 96K, and 192 KHz sample rate tests. Generally speaking, Xonar D2/D2X can

achieve arround 116dB SNR for 24-bit and 96~103dB SNR for 16bit in RMAA loop-back test.

Most important, all results can get “Excellent” general performance credits. (Please note

that though Xonar D2/D2X has good anti-noise design, the test results may have slight

deviation on different PC platforms due to the various levels of system noise interferences

and distortion, especially for 24-bit 116dB-high sensitive quality.)
