Yes. These filters are designed around trade-offs after all. Wolf's measurement differs in that he uses multiple bandwidths (currently he has 22k, 40k, 90k) while amir is only done in 90k to point out ultrasonics/leakiness of the filter.Also you're saying that the increase in distortion for high frequencies when using filter 1 for instance is inherent to the implementation of the filter?
These differences are more academic that not though, as long as all is fine in the audible range. But a proper suppression of artifacts/images is what a good filter should display. The AKM chip filters are noticeably worse compared to the better ESS ones, but they still "sound" fine...
