假如唱片完美无瑕,放音条件理想,我们就没有理由写这篇文章,一直到1978年还没有达到如此完美的程度。因此,在唱机发明一百年以后的今天,唱片放音仍是一个富有挑战性的问题。这个任务是随着整个高保真系统的不断改进而提出的。噪声、失真及其他富有挑战性的问题,在昔日的系统中还被掩盖着,今天却变成了严重的问题。例如,一个元件1％的失真几乎无关紧要,这是因为另一元件有5％的失真。可是,如果第二只元件的失真降到0.1％,第一只元件的失真虽然不
If the record was flawless and the playback conditions were ideal, we would have no reason to write this article until 1978, at such a perfect level. Therefore, the record player is still a challenging issue today one hundred years after the invention of the record player. This task is raised with the continuous improvement of the entire high-fidelity system. Noise, distortion and other challenging issues have also been covered up in the old system, which today has become a serious problem. For example, a distortion of 1% of a component is almost irrelevant because 5% of the other component is distorted. However, if the distortion of the second element drops to 0.1%, the distortion of the first element, though not
