Integrated Amp Choices

From numerous visits to audio stores in the BIG city 2 hours south of my place, and after listening to a couple of dozen speakers (up to $18,000) both passive and active. Our simple ears have narrowed it down to these 2 speakers (so far):
KEF R11s - https://us.kef.com/r11.html and Triangle AustraleEZs - https://www.trianglehifi.com/en/produit/hifi-floor-standing-speaker-ez-australe/ These 2 sound the best to both my wife, offer good value and both very close to each other in price.

Here are a few integrated amps (in around the $5K range) that I am considering and I was hoping the community can give their votes to which would compliment the speakers of choice (so far) the best?

Onboard DAC is a big consideration too, so hoping for your further comments on DAC sections as well.

Prefer new or demo over used.

Thanks,
