Default ADC without pre-ringing

Do you know AD/DA audio converters with aliasing filters without ANY pre ringing and very short post ringing?

Or propose a method of measuring impulse response of CD player or any ADC.

For example Sony CDP-XA 50ES filter "3A" is of the mentioned type.

Pre ringing can be suppressed by convolution using apodization filter which should be the last filter after AD/DA. Other possibility is Williams or any kind of minimum phase non symmetrical filter but it works best on higher oversampling or sampling rate.
