The M33 is the best of the three of those IMO. Issue at the moment is it is slow getting them due to COVID. The others will be available much more quickly.
The Naim should sound great but is lower powered than the NAD I think.
I would not pair Krell with Kef.
You could also look at McIntosh. They have all-in-one. I have no idea how stable the software is.
