Or perhaps, like mijostyn, you don't understand what these angles define.
"VTA and azimuth are two completely independent angles." Only with a tangential tonearm, not with a pivoted, offset, one. The effect may be minor, depending on the degree of offset, but it's there.Your claim can only be accurate if the pickup arm (or turntable) itself is not "true." That is, the arm cannot be raised or lowered while also remaining absolutely perpendicular to the turntable platter.
