I don't know if this will "beat" a pair of Sixpacs (with an unspecified pre-amp), but I went from a pair of Sixpacs & AES AE-3 DJH to an Ayre AX-7e and am *very* happy. However, my priorities may not be the same as yours (see my system description for details).
Also, I sold my Sixpacs & AES AE-3 DJH about a year before buying my Ayre, so there is no way I can comment on the specifics of the configurations.
