Before-and-After Data of Cartridge Adjusted by Manufacturer

Before-and-after comparisons of a cartridge that, based on my assessments/recommendations, was sent back to the manufacturer for adjustments in its cantilever angle, etc. Looking at the differences in data below, most people will have a hard time believing they are measured on the same cartridge.

上次兩個被我判定針桿太陡的唱頭之一，原廠調整角度寄回之後，今天去測了新的數據並做了azimuth等參數的微調。看了前後數據的差異，很難相信是同一個唱頭。
