I think I’d 86 the Maggi’s and went with a cone based speaker with either a ribbon or beryllium tweeter, you’ll probably be a lot closer to that headphone crispness you’re looking for.
Check out:
Fritz Audio
Philharmonic BMR
or best case scenario…Have Soundfield Audio Custom Make you a set of speakers like the MMW’s… Call AJ and discuss your tastes and needs… Not as much as you think.
Any of these should certainly will get you closer than Maggi’s to your headphones you’re using as your reference. I just got rid of my Maggi .7’s… I fed them lost of Hi Current Power and still No Attack, No the Slam I was jonesing for, sure they sounded good but dull. Nothing wrong with the sound Maggi’s project, lots of folks love em, thought I would, but panels just didn’t work for me.
I think Cones or Ribbon based speakers will bring you to your happy place.
