Theses are great speakers and deserve great amplification.
You want an amp that can do 4ohm without breaking a sweat.

Most solid states will do this, and at 91db efficient you only need an amp that can do a min of 50w more is always a better.
I suggest have a look at the Technics SU-G700 MkII (new GAN Class-D)
https://www.whathifi.com/news/technics-su-g700m2-integrated-amp-brings-flagship-engineering-to-lower...
or if you have the extra $$$ the SU-R1000 (new GAN Class-D)
that Absolute Sounds raved about.

Then there are the Pass Labs Integrates the Gryphon Diablo integrates, and the Halo Parasond Hint6 integrates
I'd prefer all these over your posted ones
