IMO you are reading too much....I sometimes do the same
you have a very fine near point source low diffraction near baffleless design in the speaker you own today and enjoy it seems except for SPL.
that is a big big hint about what you should audition.
make the investment to go listen.
i am pretty biased for being able to tune the low end for your room used Quatros would allow you to do that...
also you own some fantastic musical gear already !!!!!
