299入手了飞利浦9500，大湿说要耳放才能发挥真实实力，低频缺这么多，真的靠标准的耳放就能解决吗？ 第1页

我手里有shp9500，没觉得低频像他说的欠缺那么多。

和hd660s 对比过，这差距真没那么大，这种以价量声的也算大师？

最近和几个学音乐搞音乐的朋友聊天，说起HIFI圈的事情，他们的反应一致的，又不是专业搞音乐的要确保自己的系统和自己听到的绝对一致，air pod就算极致了，至于么。

然后给了我一个王之蔑视。

多谢邀请，却之不恭。

俺不清楚大湿和老烧有多少张画皮， 例如“在校大学生”、“工程师”以及“艺术家”等等。但是有一点是共同的。 如果您现在或者将来都没钱买电源线、墙插、排插、电处、信号线、耳机线、USB线、SATA线、网线、保险管、脚钉、地盒（骨灰盒的变种）以及量子不干胶贴纸、电子黑洞、暗物质等等 HiFi 神器， 大湿和老烧就不会有好脸色给您， 因为击鼓穿花到您这里中断了。

下面谈正经的。

首先，俺得强调， 那些劝您换线的，您得提防她/他/它们以后还会给您上其他的眼药。具体俺就不详细解释。 这 3 篇散文解释得够清楚了：

其次，耳放带来的音量的区别， 可以通过简单地调节移动设备的音量得到。 买个耳放有多坑爹坑妈坑自己， 俺就不具体解释， 这 3 篇散文解释得够清楚了：

再次， 实际能起作用的 EQ 怎么弄， 怎么达到理想的效果， 真正的立竿见影天翻地覆脱胎换骨的提升。这 3 篇散文解释得够清楚了：

（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？

有的同学念完了金光神咒， 用万用表测不到声音变大，就会认为发现了实锤。

“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”

俺必须得致歉， 因为行文松散， 俺在开头漏了关键的一句话。
“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。
这时请开始念咒。”

PHILIPS 9500 大卖， 俺不敢说自己有什么功劳， 但是俺写了不少散文。

【未完待续】
