BiAmp Focal Kanta 2 speakers with 1 set of posts.

An  EVO 400 monoblock pair with a Evo 400 pre in front driving Kanta 2s. Hell yeah!

That would be most beautiful in sight and sound.

Forget the biamp thing. Focal engineers know what they are doing. Power them up, individually, as is.

PrimaLuna is even behind the idea.

I'd be jealous.

For me, I would do the surgery to bi-amp.

Using one amp per speaker may have some benefit from better separation, and zero crosstalk.  There may be some other benefits from each amp having less responsibility and it's own power supply.

Ahh got it. Yeah you could do that. I doubt it would bring much gain for you. They are fairly efficient. 

Yes they are switchable to run in mono.

Correct you cannot bi amp or bi wire.
