what's a good Gan / Class D option under 3k? Nilai or Ncorex500?

I was on the VTV amplifier page and a bit overwhelmed by all the options

I like a fast energetic amp with lots of power

I want something that I can use as a tool to test a variety of different speakers in  2 channel application

The NcoreX500 modules appear to be just about right but then I noticed both VTV and Deercreek audio carry the Nilai modules which are apparently even better?

any suggestions/advice?
