Maggie MMG versus Ls3/5a

Mapman, I'm glad you talked about low volume performance....that's important to me. I'm encouraged to pursue this direction now. Is it a better idea to purchase new MMG or, there is a pair of SMGa locally for sale here, at about half the price of new MMG

… Mapman says MMG are good on transients and attack, but Polarin says they are not great for rock because they lack weight and dynamics and Rpfef says they have greater impact (than the LS3).

How do I tie these opinions together to get an overview...?

Add a subwoofer or the DWM panel.

Then you'll get transients & attack plus the bottom end drive you need for rock and pop. I'm using a pair of small fast subs with my Maggie 1.7s and they pretty much cover all genres of music. If I need more slam for synth-pop and heavy rock, I would just swap out the little subs for bigger and deepter ones.

If the Rogers you heard did not present a deep and realistic soundstage they probably didn't have the proper electronics.

To clarify: I meant that at the time I auditioned the Mags vs. LS3s, I found the greater radiating surface of the mg1s and their ability to play louder made larger scale musical forces more immediately physical in their impact. I guess, for electric guitars and drum kits, neither option suffices to give a great rendering.
I thought both designs had about similar detail revelation and transient attack. The 'tiny' drivers and the little box make a satisfying job of quickness surely not very different from that of the planar designs.

Difference between soft and loud and dynamic range.
