I’m looking for suggestions of speakers with equivalent or better sound....
What the maggies could do better are better dynamics, bass weight and so forth
Magnepan is s unique speaker for which there is no clear substitute. Do you have any electronics that will do proper "bass management"? If you do, set each sub right next to each Maggie in the front stage and keep going higher in crossover somewhere until you hit 120, 140, 200 hz, etc.
"Bass Management" means anything under that crossover freq will be lopped off from reaching the Maggie and only sent to the subs. You will also have the ability to delay the maggies and such. If you have purist electronics only, you won’t have such capabilities.
When you do such experiments, i.e not giving maggie a full signal and restricting it from moving too much to produce lower bass octaves (done only by the sub now, the right guy for the job), everything can feel more dynamic, more bass weight, more resolution will pop up, etc.
Never make a Maggie move too much.
