[#38] 一個銅環原來對音色都有很大影響    
Found this in other forums for anyone who is interested.

"銅片是在新填地街290-350號稱左近買
原本12x24 1.2mm的碎料$200. 開料每刀$15."

是否一定要用銅呢?
在超市買的錫紙, 剪一塊來包住個插頭, 是否同樣有效?

我在本地的家用店買到2" 及1/2" 銅管多個。大的放在CD 的 pc 上,小的放在RCA。背景靜了,多了丁點弱音。再放多幾個真是不濟,聲音變得呆滯。

用錫紙一試? 好提議。

也去買了一個紅铜環,2吋長/1.5吋闊,套一在絛PS audio 電源線個Wattgate female 電插上供電給那個integrated 膽機, 效果同幾位朋友十分接近,背景是明顯靜了,音塲是深了點,空間感多了,樂器聲整齊了,低頻緊了而少了豐滿感示"音樂味",有點像alman說的呆板.



相信用不同金屬套會有不同音色.紅铜環會加了點紅銅温暖的音色.於鋼琴聲尤其容易聽出.不過銅環要緊貼着機殼,互相接觸.在我的情况,銅環只可接觸到機後IEC插兩邊的鏍絲.

>>>在超市買的錫紙, 剪一塊來包住個插頭, 是否同樣有效?

我前日試過,對摺再對摺共8層家用錫紙,可是聽不出分別.

另外,有些銅水喉,應該夠大罩住個尾插,可去五金鋪找到,不過賣親都斷尺計.

Very interesting and informative findings.

Shielding: I'm looking for opinions from brothers. For diyers, how about having the IEC cable end be covered with those flexible knitted mateljackets and have the jacket connected with the ground of the power cord? (something like the the jacket for SOMMER Stratos, if you know what I meant).

That come to my second question, if your power cord is properly shielded, would you still need the bass ring?

I know that Audioquest have high-end battery-powered shielding, however, I don't know how to diy.

To have the IEC cable end covered with "those flexible knitted mateljackets" and the jacket connected to the ground of the power cord is worth trying.

"Second question, if your power cord is properly shielded, would you still need the bass ring?"---

Even when power cord is properly shielded, it esn't include/cover the power plugs at both ends.

Just my humble opinions.

一定要貼到機殼嗎?

I am not sure the copper ring actually need to touch the chasis, even if it cannot be done, one can use a small wire from the copper ring to the chasis. Mine can only touches the screw of the IEC. Anyway might try to use a lead wire and see if it makes any different. 1.5 inches copper ring (or call reducer or coupler) should be readily availble at hardware store that sell metal pipe but anything bigger than 1.5 inches in diameter then try your luck. One can also put some sound absorb material for the damping as well (or as a way to firmly cover the IEC plug). Can anyone also upload some of their copper "ring" to share?

Good luck.
