I was testing my Hercules Fortissimo III under Windows XP using Rightmark Audio Analyzer with an external loopback tests and got the following results:
16-bit, 48KHz
Frequency Response: +1.05, -0.74
Noise Level: -86.8
DR: 86.7
THD: 0.0081%
Intermodulation: 0.014
Crosstalk: -86.2
IMD: 0.022
Then I compared them to this review at Digi-Life which got the following results:
Frequency response (40 Hz to 15 kHz), dB: +0.05, -0.03 Excellent
Noise level, dB (A): -86.5 Good
Dynamic range, dB (A): 86.3 Good
THD, %: 0.0035 Very good
Intermodulation distortions, %: 0.014 Very good
Channel crosstalk, dB: -86.1 Excellent
The only notable difference is in frequnecy response, but it's quite large. I was hoping someone might be able to give me an idea of why this would occur so I can resolve it.
The PC that this soundcard is in is regularly used to listen to music and movies for my home theater (webpage link at bottom) and sound quality is important to me.
