I run Magico S5's in my mixed 2 channel audio/HT setup which are a moderately difficult load & am quite happy with the bottom end. My current Vitus SIA-025 has plenty of power for 2 channel audio at the volume levels I listen at, though ideally i'd like a bit more control for HT duties. But rather than add an active sub or change amps, over the next 2-3 months I plan on upgrading to Magico S7's which dig down to 20Hz & are about 1db more efficient than the S5's, so they should be awesome in both disciplines.
Your EA MM3's similarly dig down to 20Hz & are capable of moving a lot of air. In the case of your system, I don't think you need subs unless you want to set up a full on HT system.
