（中文在後）The Decca family of cartridges are often said to have poor tracking ability. In fact, with proper anti-skate force, at least in standard tests they track better than many MC cartridges. But when they mis-track, the distortions are more offensive to ears. Here in the first spectrum chart taken when running a typical tracking test, the old SC4E shows the typical Decca-family behavior of having higher 3rd harmonic distortion which is less pleasant than the 2nd. This is just the opposite of most other cartridges. In the second chart, the SC4E is put through the maximum signal strength of +18dB and it still manages to play through the whole track with manageable distortion levels, better than many MC cartridges.
