飞利浦 Philips SHP9500 不需要换线, 换线不能提供人能察觉的改善。

飞利浦 Philips SHP9500的线两头都是 3.5mm, 即使被宠物咬断了也很容易更换, 一元店都能买到类似的 3.5mm-to-3.5mm 转接线。至于有些人说:“最近发现线材对THD影响也不小”。是的,线材对 THD 影响也不小,而且可以测出来, 如果用ppb 做单位的话, 数字的区别就更大了, 因为 ppb 里面的B 是十亿的意思 。如果您还能被洗脑接受 “9500 需要换线”,那么请跟着老麦默念 1,000,000,000 遍 “信仰万岁”。

当然,觉得 “信仰万岁” 四个字太草率的同学, 不妨看看下边的咒语。

您可以通过默念一个具有上千年厚重历史沉淀和文化底蕴的咒语来达到换发烧线材一样的奇效。俺把这个咒语贴在这里, 方便各位取用。


金光神咒

天地玄宗万气本根广修亿劫证吾神通 三界内外惟道独尊体有金光覆映吾身 视之不见听之不闻包罗天地养育群生 诵持一遍身有光明三界侍卫五帝司迎 万神朝礼役使雷霆鬼妖丧胆精怪亡形 内有霹雳雷神隐名洞慧交彻五气腾腾 金光速现覆护真人 急急如律令


**请注意这个咒语要用方言唱诵

例如潮州话、闽南话、福州话、客家话、广东话、四川话,不宜用普通话(Mandarin),

切记。

这是可以测量, 然后用小学或者初中的数学计算出来的。


您可能会好奇 Philips 9500 的原厂线的分布电容电感电阻及耳机单元电抗等等参数。

俺已经测好了。 如果需要, 请复制粘贴。

有同学反映, 手持的电容电感表太 LOW, 手持的交流电桥太 LOW, 测出来的东西不够有说服力。 老麦不禁暗叹一声, 不是每家每户都常规自备八位表六位表 THD 表 GHz示波器 航天级充电器。。。自备扫描隧道显微镜以便去怼大湿的。 这科普的成本真大, 怪不得大家都选择沉默。

(很业余的ARTA) 测出来的 PHILIPS SHP9500 的阻抗vs频率的变化。 结果如图:

PHILIPS SHP9500 Impedance values for 480 frequencies

Frequency(Hz) Magnitude(ohms) Phase(deg)

100.575 48.045 -1.672

119.577 46.241 -5.152

121.314 46.050 -5.386

996.130 34.372 -1.940

1010.599 34.006 -1.393

10009.300 35.777 12.775


。。

看到这里, 发现老麦的重大错漏了吧?

原厂线的电阻没有测!

赶紧补上~~~

SHP9500换根线声音能变大多少?

如果这条线是超导体的话,应该可以变大 0.3dB, 也就是 300 mdB.

如果用 ppm 做单位 + 这条线是超导体的话, SHP9500换根线声音能变大 30000 ppm 左右。

如果用 part per trillion (ppt) 做单位 + 这条线是超导体的话, SHP9500换根线声音能变大

300 000 000 000 ppt 左右。

这就是大家期望的巨大的提升, 如果发烧线是超导体,

能提升 3%。


惊喜不惊喜, 意外不意外, 开心不开心?

当然, 您把音量稍微开大一点点, 用原线也能达到超导体同样的效果。
