To also cherry pick the data, the ASP 500 module, the 'big guy' in the series was down 1/2db or so at 20khz. This produces notable phase shift in the audio band. And, if it matters, really odd looking 10khz square wave response.
I'm not going to try to find the measured data. You can find it if you are really interested.
