Depends on whether you want the additional features offered on the 616 which only uses the most basic version of Audyssey 2EQ which cannot EQ a subwoofer, or the better audio fidelity from the 1913 which offers the more advanced version of Audyssey MultEQ with 2x the speaker control points of 2EQ as well as the ability to EQ a subwoofer? Your choice.
