what cables are you using? more power would be great, two subs would be great, sure. but i would make sure that you're getting all the bass you can out of your system first to see where you stand.
i've never owned maggies and i don't know how sensitive they are to cables, but all the speakers that i've owned have been very responsive to different cables, particularly where bass is concerned.
i would think that the s300s would be able to get close to getting the lowest bass out of those speakers at low volumes, but (at least in my experience) that assumes that you've got good speaker cables and power cables on your components.
in my system, power cables on the components are as important as speaker cables for bass. recently i just got some nice (cryo'ed, for what that's worth) adapters to allow the use of 15amp power cables on c7 connections (those little 2-holed connections found on playstations and mass market electronics) and the difference on both my ps1 cd player and my hd cable box was great - the primary benefit being more bass. the two components had already been using a ps audio punch cable, which was a night and day difference over the tiny, stock cables, but using an even bigger/better cable was another jump.
so i would make sure all that is in place before spending tons on new amps.
