Gryphon Diablo 300 Integrated or Dartzeel LHC-208 Integrated with PMC Fact 12 Speakers

Thinking about upgrading my Hegel H360 integrated Driving PMC Fact 12 speakers (84db). Running Aurender N100H streamer or Hegel CD player through an Aqua Voce S3 DAC. Speaker cables are Transparent The Wall Plus. Have also driven these previously with a Krell 400i integrated. Both have been good, especially with the Aqua DAC, but auditioned both the Gryphon Diablo 300 and Dartzeel LHC-208 recently and was blown away by both. Listened through an Aqua Formula DAC and Wilson Sabrinas (which I believe to be somewhat similar to my PMC Fact 12's). Wondering if the Dartzeel, which was just a tad more detailed and "organic" in my view, would have enough wattage to drive the Fact 12's (obviously the Gryphon would have no difficulty with its 300 w output). I listen mostly to acoustic music (guitar and vocals) but enjoy a wide variety of genres if well recorded. My listening room is a den approximately b12' x 15' with 10' height ceilings. I have about 2' separation from side walls and 3' from rear wall to speakers. Both the Gryphon and Dartzeel are in the same $16K price range.
