Best class A+D amp with Conrad Johnson PV-14LS SE pre-amp

Downsizing and looking at smaller amp packages to mate with a CJ 14LS SE pre-amp (hybrid) 

So far it comes down to the following;

 NuPrime ST10; PS Audio Stellar S-300; Channel Island C-100S.  All within almost same price: $1400- $1600.

One other possibility is the Schitt Audio Vidar which is not class D, and more like a class AB amp at  $799 

Thank you,
