None of the Chinese brands seem to be using Hypex or Purifi. Some Emotivas (I know, not a Chinese brand) use IcePower. I might accept IcePower performance to get a nice meter, depending on price. At some point you can just put Hypex modules in one of the really nice Chinese Accuphase clone cases, which I have also considered. I don't really like amps without meters. If I were to get some, it would probably be a pair of Schiit Vidars, or Benchmark, but I don't see the point if they lack good meters. Might as well keep running my tube gear or Marantz 22XX series stuff since it looks cooler.
