Audiophonics Hypex Amps

I was looking for more options for my new amp and found those new audiophonics Mono amps that are based on hypex modules.
They also have an amp that’s based on the NC400 module and also costs 700€ like the kit. I think they planned to even make a NC500 OEM amp.
But they also had an amp based on the NCORE NC500MP module and I wonder how that compares to the NC400. Will the NC400 be a much bigger step up since price difference between the mono amps is 250€.
