商家的这种标法其实是欺诈，用户关心的是你实测的整体数据，标个芯片的理论值管屁用。 [/B]
也可以了，据实测，至少在 110 dB 以上。这是三千元以内唯一一个实测可以达到 110dB 的卡。
ESI 的卡都是这种标法，但是国外也没有提出异议。Sound On Sound 在评测 Wami Rack 192X 的时候，也没有提出标法的异议。
Sound On Sound 在评价 Wami Rack 192X 的回放音质时这样说：
I was impressed by the audio quality of the 192X, and after months of auditioning soundcards with very similar converters to the AK4528s in my benchmark Echo Mia, it was refreshing to hear some that sounded slightly different. These had a subtle 'forward' quality at the high end, giving strings and percussion a sweetness and sheen. I suspect once again this was also partly due to a low-jitter clock, since transient detail was more defined and focused, and I could hear further into reverb tails.
在评价录音音质时这样说：
The mic inputs sounded clean, and my experiments with 96kHz recording displayed an open, airy and natural sound. Switching to the 192kHz setting provided an improvement that was at best extremely subtle to my ears, although its claimed frequency response of 6.5Hz to 87kHz (±0.007dB) should preserve detail that might be lost at lower settings. Personally I think that moving beyond 96kHz is of questionable value unless your mics, acoustics, mixer and so on are of first-class quality, but it's an option if you want to try it.
Background noise with the front-panel gain controls set to their minimum 0dB position measured -93dB RMS with 16-bit/44.1kHz recordings, dropping to a very good -107dB at 24-bit/44.1kHz, opening out to -105dB when the bandwidth was increased to 96kHz, and -102dB at 96kHz.
注意，Waveterminal 192X 的录音音质基本与 Wami Rack 192X 一致，我实测的时候在 44.1 / 16 下的静噪也是 -93dB RMS ，与 Sound On Sound 的实测结果一致。
然后 Sound On Sound 标示他的音频性能，其中有
Input dynamic range: 123dBA at -60dbFS.
A-D converters: 24-bit 128x oversampling, full differential input.
D-A converters: 24-bit 128x oversampling, 8x digital filter.
Output dynamic range: 106dBA.
Frequency response: 6.5Hz to 87kHz (±0.05dB) at 192kHz sample rate.
可见对于 ESI 的标示法，国外并无异议。
