The Anniversary is brighter The 55 Hz is less bright but still bright enough. The 55 Hz has more bottom The Anniversary has more high mids The 55 Hz sounds slightly scooped in comparison with the Anniversary The 55 Hz sounds quieter at the same level of the Anniversary (I don't think this is an efficiency thing. I think it's a frequency band thing) After playing the 55 Hz for a day or two, I still leave open the possibility of going back to the Anniversary. I hope this helps anyone considering these.
