I would not think the Be driver Kanta and the Purifi based NAD would be an ideal combo. I would think it would sound a lot like the SimAudio 860 amp and Paradigm Persona 5F I demoed once. It was great for about an hour but not for long listening sessions.
When I was thinking of a Be driver-based speaker, I was looking to use a warm-ish amp such as Krell XD, Parasound, Anthem STR, Pass Labs, Coda.
