Upsampling MQA files to original resolution with sox will sound like the original resolution

What I’ve read several people who have looked at MQA say in this forum in various threads is that the MQA filtering doesn’t cut sufficiently to get rid of the post-ringing.  You say that it does get rid of the post-ringing to such an extent it sounds “thin.”  Can you show or describe the cut in the filter that gets rid of the post-ringing (for example, how many dB down at what frequency/ies)?

Already at http://src.infinitewave.ca for three filters in an earlier version of the software.
