| | Surround Professional 2002 - Craig Anderson; DSD to PCM Comparisons |
 | | Turning to the DSD trace (Figure 5, right), Anderson found that “The DSD trace does look very similar to the picture in the Phillips brochure, and represents the square wave better than the first two PCM traces [at 44.1 and 96 kHz].” But when compared with 192kHz PCM, DSD performance proved very similar. |
 | | Overlaying the DSD and 192 kHz traces (Figure 6, right), Anderson pointed out that the difference in rise time between DSD and 192 kHz are “statistically (and perhaps audibly) insignificant.” Also, both accurately extract the first and third harmonics from the square wave. |
 | | However, Anderson attributes the primary cause of the DSD “blurring” shown in Figures 5 and 6 to imprecise traces along the vertical and horizontal axes, which are much more significant than any noise superimposed on the traces themselves. |
