Amps to match kef blade2

I recently bought a pair of blade 2 from local dealer. I'm driving it naim nova. I don't like a lot of boxes, would accept one streamer/dac + one integrated amp or a better one box solution like nova. Currently looking at hegel h590, gryphon diablo 300 and luxman 509. wonder if there are better suggestions or help me choose which one should I buy.
