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.
BiAmp Focal Kanta 2 speakers with 1 set of posts.
I have a Primaluna EVO 400 Amp and Preamp and Focal Kanta 2 Speakers. I think it would be an improvement to add another Primaluna EVO 400 and run them in mono. I was told it was not any good unless speakers had 2 sets of posts, 1 for the High and 1for the lows. Any help out there?
