looks like this is a change for the sake of a change & that there's nothing insufficient in the M-L Spire for your particular listening needs.
I was never an advocate of change for the sake of change but then the audio industry survives on this motto (the merry-go-round effect).
The Hybrid ESL from M-L will have quite a diff bass playback compared to the full planar Maggie. Ribbon/planar bass is very different sounding than cone bass & often people cannot make the change willingly. Planar bass is tight, fast & has excellent tonality but does not always have the slam of a cone driver bass (depends on the amp driving the planar). Your integrated amp says that it can drive 2-16 Ohms & that peak o/p current = 35A but one would have to know how big the power xformer is & the model number of the output transistors to know just how much current it can really dump into a very capacitative load (which is what your ESL panel & the Maggie look like to the amp). So, be wary of this - hear the Maggie in some dealer in your local area or if your are in some other location due to vacation or business travel.
IMO I never thought much about any M-L hybrid speaker tho' M-L Statement E2 speaker was really something very, very nice sonically. Big price difference hence big (improved) sonics, naturally. Of course, YMMV since you like the Spire model. This is all good - you must be happy with your own audio gear.
