I have often wondered why the frquiency responce for the empeg wasn't listed anywhere, I like my empeg but I can't just tell my friend its better "because" because is not an answer anyone have real hard facts I can tell him. the soundcard he wants to use has these numbers

Audio Performance

Signal-to-Noise Ratio with AES17 filter (A-Weighted)
2V Rated Output 1V Rated Output
Stereo Output 108dB 102dB
Front and Rear Channels 108dB 102dB
Center, Subwoofer and Rear Center 108dB 102dB

Total Harmonic Distortion + Noise at 1kHz (AES17) = 0.004% (1V, 2V Rated Output)
Frequency Response (+/-3dB, 24-bit/96kHz input ) = <10Hz to 46kHz (1V, 2V Rated Output)

Quote:
Based on both being EQ'd properly, they would sound indistinguishable from each other.

The empeg is better in about a thousand ways that have nothing to do with the sound quality.
