2) and at the very least, videos C & D are from a different distance than A & B.
3) Video B has a set of speakers now on the table right next to one of the new speakers playing, no doubt this has some effect on the frequency response.
4) Video D is using a different amp
5) Speakers in Video C are spaced way differently and sitting next to other speakers would would change the response
6) No way to tell the differences in the playback volume

Do you know for a fact that all the videos have the exact same compression, or are you guessing they due based on the fact they are from the same person?

How is the only variable the speakers?
