If you like the Sophia then my suggestion would be to stick to simpler three ways rather than Appolito designs (which use two midranges to increase output/avoid compression but all suffer from lobing issues). You may prefer the sound of the Sophia's simpler design (even if it may lack the dynamics of a big Appolito, such as the Temptation).
I'd suggest Dynaudio Saphire as an option or if you want more dynamics (less audio compression at higher levels) then go for PMC and ATC three ways. I may be reading more into your preferences than is justified but remember two transducers making the same sound and sitting side by side inevitably produce lobing - it can be a pleasant spacious sound but inevitably the reflected soundfield from floor/ceiling will not match the primary field and you may lose some "naturalness" on the sound...of course you gain spaciousness, better dispersion control and more dynamics...so like everything we are taking trade offs here. Two cents.
