@devinplombier You should NOT do what you did. By playing the recording back through your system you are doubling up on the room contributions which will have constructive and destructive interference. You need to listen to the recording either in near-field or over headphones, not recommended. Your process of playback used for comparison is very flawed so I’m not surprised at all by the discrepancies between the native playback and recording playback through the same system, and listened to at the listening position. You should listen to the recording in near-field preferably than over headphones because by listening to it near-field you will incorporate the Head-Related Transfer Function (HRTF). When you listen with headphones you skip/omit the HRTF and that will make the audio recording sound different, than what you would hear if you were sitting in the room at the listening chair/position.
To put yourself in the listening position as heard if you were there then listing to the recording in near-field is the only method.
