Oratory's measurements are for EQ not for review, I guess I should have specified I meant within the context of reviews. The rest absolutely are as I described, presenting overly smoothed measurements to hide imperfections, some don't even post distortion measurements or present them (and frequency responses) in misleading ways. Harman's research was done on the GRAS but reviewers are increasingly talking about the B&K 5128 as being superior to the GRAS and switching to it misleading people into thinking the GRAS Harman curve is 1 to1 to their approximation of the curve on the B&K. Amir and Oratory are the only ones actually following the science
