magnepan mmgs-buy zero autoformers or stands 1st?

Your speakers may develop a bit more nuance and the bass may "tighten up" a tad but don't delude yourself here.

Earthshaking, paint-peeling bass is not a characteristic of the MMG or any other Maggie for that matter but then again you knew that prior to purchase.

I understand, but that speaker has severe limitations in the bottom end.

Don't kid yourself.
