Discussion Of Results
This card, while branded so as to appear to be the logical sucessor to the Ensoniq AudioPCI, measures up with slightly degraded performance. The degradation is probably most audible in the area of frequency response. One difference is the use of a 1371 DSP and an AK4540 Codec, in place of the 1370 DSP and AK4537 Codec in the original Ensoniq AudioPCI. The Creative Labs Sound Blaster 128 seems to be a closer match to the EAPCI, performance-wise.
