I use a PSAudio Integrated of 500x2 @4ohms into MG1.6s.
Bass is only OK.
If the MG12s follow Magnepan practice there is NO big dip in impedance and the phase angle of the load is moderate throughout.
Load sensitivity of an amp is a function of design, not the topology of the amp.
Good / bad designs, at least as far as driving a reactive load exist in all schools of design. For non-'d' amps, or even 'd' with non-switching power supplies, I'd start by looking at the sheer size and weight of the Power Supply.
Your new panels will only go so low and if you want some bass slam, you'd be well advised to at least demo a sub.
