Urbie here is our "final" take on this subject.
You can't expect the same gear for the one gentleman who owned Personas and then switched to Monitors to work equally well for both loudspeakers.
This is especially true with Home Theater gear which tends to not sound anywhere as good for Music then Home Theater, which would make the Personas most likely sound way too sharp.
Unless that person was using a really good Home Theater amp, voice for music the sound could be horrible.
The Personas are a brighter loudspeaker vs the Monitors which are a duller loudspeaker. If you look at both reviews you will see that Monitors AMT is rolled off in the top vs the Personas which has a rise in the top end.
Therefore if you used brighter electronics on the Monitors to help bring out the top end you would sizzle your ears with the Personas.
The same way that the Personas benefit from warmer electronics and cabling, therefore the warmer matching components that would work with the Personas would make the Monitors totally rolled off and uninspiring.
This is where pronouncements about brand X being better than brand y fall down, you are demoing a system, the same way that a Ferrari engine transplanted into a Toyota doesn't make the Toyota a Ferrari.
Monitor audio makes a fine loudspeaker so does Paradigm, which you prefer is up to you.
There will always be fans of any particular product the smart guy or gal recognizes their own biases but comes at audio with an open mind and as we mentioned previously just because you hear product X at a dealer doesn't mean that it is setup correctly or with the right gear.
Go listen to the product at many different dealers or ask the dealer to swap a component and or components and see what changes.
As we recanted on another post just changing one board on the dac in a $150k Persona setup made that same system sound like an entirely different one, as all parts of the system must work together in unison.
You can have the best speakers, electronics and cabling and the wrong source can torpedo the entire system.
