Opinions on Nuprime vs D-sonic vs Red Dragon vs Class D Audio


I'm looking to try a class D based power amplifier. Please share your experiences with the NuPrime, D-Sonic,  Red Dragon or Clas D Audio lines of power amplifiers. Thanks!

Does anyone know if Red Dragon is still a viable company?  Seems they were MIA even back in early 2019 as scratcha said. 
They seem to be sold out of everything.
I have emailed them with no response for a few days.  I am considering buying a used one and don't know if there is any support to speak of from them.
