Paradigm Persona 5F:
$17K? Oh hells no.
1" Tweeter, 7" Mid, three 7" woofers.
Aesthetics: some shape, not too boxy/square.

Pretty accurate until after 8kHz. Some people might have issue with the rise in treble from 6-10kHz.
Impression: For $17K MSRP, I expect a lot more. It doesn't "look" like a "17K speaker to me. Specs are kind of similar to the Focal, except the Focal is $4K less MSRP.
So of the 3, I would probably go with the Focal.
