Could be true if the load is the accountant . Ncore are supposed to have a load independant response, not the case for Pascal modules.
I found where I read those statements:
"Duntechs, with their multiple drivers and complicated crossovers, are a very difficult load," Mytek's chief designer, Michal Jurewicz, told me. "Hypex [class-D modules] cannot drive it, the amps collapse, but this Brooklyn Amp does it with ease. This came out during months of design tests I did in 2016, when we were testing many different circuits." Jurewicz also said that Mytek spent six months experimenting with more than 15 class-D amplifier modules from various OEMs, upgrading parts, adding capacitors, adjusting circuit parameters.
While obviously not SOTA, Mytek gear is reasonably well-engineered. I find it implausible that Jurewicz would make this up and risk a defamation claim.
