Of the three you are considering, the Cary could not be more different than the other two...
The Marantz and NAD are a solid state class A/B.
The Cary is a vacuum tube.
Right now I would say the Cary, being a tube amp, is a little light for your current 4 ohm speakers. Either the Marantz or NAD would do a better job driving them.
Being a Marantz PM15S2 owner, my choice would the Marantz PM11S3.
It doubles its output into 4 Ohms, and is heavier than the NAD. Its build quality is second to none being built at the Marantz reference factory in Japan.
Hope you get more feedback from other members.
