根据第一阶段调试结果，从海外订制了一批元件。经过20多天的等待，今天这批毒物终于到位。分别是mundrof 的银油电容、铜箔电容、EVO oil 油浸电容，以及mudrof的金银高保真电阻、镀金接插件，Jantzen 银箔电容、Superior Z-cap红皮电容等。

其实最毒的应该是下面这一对电感：Mundrof 10AWG的铜箔大电感！
   这对Mundrof FC 系列铜箔电感采用OFC无氧铜材料，10AWG的铜箔截面积有4.9mm2，内阻极低！那么大的电感量，内阻还不到0.2欧，铜箔高度77mm，一个电感足足近3斤重，花费颇巨。希望这对电感的加入，对低音量感和控制力，以及声音的音乐感、细节、密度和中高频延伸有显著的提升。

从阿明兄这么多年的折腾经历来看，最终结果似乎已经不是那么重要了， 这个过程的酸甜苦辣才是最宝贵的。

希望阿明兄不断更新。。。

这个DIY代价也非常高！更大的代价是个投入时间！

希望用平价的元器件做出好听的箱子，老是高价的电容电感上去，成本太高。

一分钱一分货，不投入怎么会有好声。支持折腾

对元件的选用，确实经过了不断深化认识的过程。刚开始是一味的使用补品元件，以为有了好元件就可以有好效果。后来才认识到分频电路设计合理、数值正确才更重要。最后来，明白各种元件都有其特点，没有一种元件是全能的，合理搭配是门学问。但不管怎么说，这几点规律是共性的：
1、高级元件比低档元件可以给我们提供更多的信息，特别是同厂家不同档次的元件。比如有些低档电容初听厚暖，但是和高档电容一对比就会发现这种厚暖是带有砂砾感、粗糙的声音，而且少了很多细节，音乐的空气感、堂音、余韵不足，特别是围绕在乐器周边那种金黄色的光晕、那种毛绒绒的感觉基本上是没有的。
2、在分频器元件上多投入些，其实性价比是非常高的。在电路参数正确的基础上，将电感、电容用上更高级的元件，可以有更好的低音量感、更好的控制力和弹性，更大的规模感，更好的质感、密度、活生感，整体声音更流畅、更高贵、更大气!如果为了提升这些hifi要素，而升级线材、功放的话，可能需要成千上万元才能达到。

3、在音箱到达一定素质、声音平衡后，任何一个元件的改变都对声音有着巨大的影响。前些天我把箱内接线柱连接到低音喇叭负极的单条0.5米长的杂牌换成和正极相同的cardas黄金比例线，声音一下子变得流畅了，多了很多水分，原先有些杂乱的乐章也变化好听了很多多。声音变化之大让我以为换个了音箱。这次将低音电感L1011从原先的solen七芯电感和Jensen 12AWG铜箔电感串联的换成Mundrof 10AWG 大铜箔，声音变化更是脱胎换骨，声音变得厚暖、从容、大气、富有弹性自不必说，早在预计之中。没想到的是换上Mundrof 铜箔后，整个声音转换成为金黄色的暖调，带着酥甜、芬芳气息，就象是最顶级的电子管机器，但又没有任何的糊和乱，稳定性和条理性也极好，好听极了。我不知道是不是因为Mundrof 铜箔无氧铜、高纯度铜的原因，还是Mundrof有着独家制作密技。可以说Mundrof 铜箔电感和它家的银油电容声音走向完全不同。

4.要极度重视旁路元件对声音的影响。比如在低音电路中，我将RC旁路电路中的R1021从Mundrof 绿皮电阻换成它家的金银高保真电阻，声音的提升也是巨大的。另外，对于RLC陷波电路，一般认为可以用低档元件，但我将RLC回路中的C1051电容从Jantzen 兰皮电容换成Jantzen 红皮电容或M-cap EVo OIL电容，声音改变都是巨大的。高音旁路元件也一样。我曾将高音的RC回路中的C2071小电容（低于1UF）从jantzen 银箔电容换成jantzen 红皮电容，声音的清晰度、质感都有明显的降低，要知道这个Jantzen银箔小电容只比红皮电容贵了几元钱，就在解晰力上有明显的改善。所以经过几年的折腾，反复对比之后，确实很难回头使用低档的元件。

5.各种元件都有它的特性，如何组合使用是门学问。从性价比方面考虑，现在基本上不再使用太贵的元件了，比如，每个电容都有它的优缺点，如M-cap evo oil 在中频质感表现较好，适合vocal（人声和乐器）的还原，但略有点砂砾感，透明度方面也有点暗，而Jantzen superior Z-cap 流畅好、中低频量感多，但全都使用它又可能会太滑溜了，所以我一般会采用几种电容组合使用的方案，以实现全频段的良好还原。
  最近看到一款杜兰Duelund CAST-Cu-Ag Hybrid Loudspeaker Capacitor分频器专用电容，也是采用了在制作时就将主电容（铜箔电容）上直接并一个银箔小电容的组合方案，国外玩家给了它15分的最高评价。莫非俺的认识水平也和杜兰一样高了？



Technical specifications (according to manufacturer): "Inside the Duelund CAST hybrid silver-copper capacitor there are two capacitors: a main copper foil capacitor that is bypassed by a small silver capacitor. They are both potted together. The lead-outs are intertwined from both the pure copper foil capacitor & the pure silver bypass capacitor hidden within the CAST potting. Premium VSF-CAST speaker capacitor; pure copper / silver; handmade in Denmark."

Sound: The CAST copper silver hybrid capacitor is very similar to the pure copper version but with added top end openness. The hybrid is same as the CAST-Cu in regards to having an extremely neutral tonal balance with very life like harmonics, especially audible with acoustic instruments but things ssem a little clearer, more "there". For example, William Lawes' "Consort Sets in Five & Six Parts" (performed by Jordi Savall with Hesperion XXI) is known for it's rich and structured nature, with the Duelund CAST-Cu-Ag Hybrid this layered form of music becomes more obvious, more tangible than with the pure copper version. It seems like the silver content makes the top end "shine" a little more, making it easier to differentiate between all the rich harmonic overtones this type of music is well known for. In direct comparison to a Mundorf Supreme EVO Silver Gold Oil they sound darker but that is only relative because the Mundorf focusses on the top end with (to my ears) a little too much energy. The Duelund CAST-Cu-Ag Hybrid simply sounds so much more like real music to me, more intimate as well. The Duelund copper silver hybrid has a natural ease, is just about tonally perfect, spatious, smooth and open at the same time. Comparing it with the lower cost Duelunds such as the Rs-Cu, the RS seems a little "calmer" and less well defined in the top octave. Now, I did find rating this capacitor to be a little difficult because one could be inclined to say that the Duelund CAST-Cu-Ag Hybrid must be "at least 2 points better" than the Duelund CAST-Cu, especially after having such great results with Duelund's seperate 0,01uF pure silver bypass capacitors. I would be more inclined to say that if you have a system that is performing extremely well, tonally well balanced, coherent and musical and you want to get some more "life" out of it, the Duelund CAST-Cu-Ag Hybrid is the only way to go. As from now I will be supplying the Plutone loudspeaker with this capacitor as an optional extra. That prooves just how good it is. You won't be dissapointed :-)

得，看来调音确实是细致而漫长的路啊，劳力还是小问题，心力耗费无数啊。

期待成品的出现

阿明兄，除了陷波电路，和电感串联的电阻是不是电感的直流电阻？

同期待，哈哈

同意阿明出商品成品音箱，就像潘主编一样，当然要比他做得更优秀
