Depends on whether or not the target used in that comparison was for 5128.I'll have a read of that RTings report, but I just wanna say by-the-by here that it's not valid for them to overlay the Harman 2018 curve over their spread of B&K 5128 target curves, because Harman Curve is only valid for GRAS measurement rig, so it's not valid comparison.
It looks like it was the one from GRAS in which case they indeed cannot be compared.
A single (averaged) target curve is not scientific either. Best would be to show a tolerance band with the remark that there should not be substantial variances within 1 or 2 octaves.
