[#27] 一個銅環原來對音色都有很大影響各位師兄，睇完片後覺得是否Marantz的機無地線，所以加條地線才有用？我地d機已有地線，再加會唔會係多餘？		heman123 正式會員 218.xxx.xxx.181	2009-03-22 12:21

更正
成套器材只要一部機落地就足夠,但必要睇說明書設計師設定該器材是否需要落地(即跟原廠設定).

銅環五金舖$15/pc,玩下無所謂,但不要亂改器材接地設定

嘿...銅管不好買,人家也不一定幫你切
所以我先來大概實驗一下,現在來分享心得

道具很簡單就是一個可樂罐
用罐頭刀去頭再用剪刀剪開(要小心,切開的邊緣是很鋒利的)
之後就開始測試

圖片可以看到,可樂罐是大蠻多的...沒辦法像短片一樣合身
測試很簡單...套上去,試聽...移開,再試聽...再套上再試聽

差異其實很微細...但差異也很微妙
音場好像略為縮少,感覺細節少了一點
但是,人聲凝聚變強,毛邊變少,
低頻...尤其是低頻,結實太多...量感不變但層次分明
我認為這是很優的表現,而且它幾近不換錢
當然,這比較適合細節已經足夠又或低頻雖然加強控制的系統

而這個實驗,我只試用在CDP而已
效果已經讓人滿意,我想要去找一下適合的銅管或是鐵管了

銅管 is not easy to find especially you need around 2" in diameter in order to cover the IEC plug, not very common but I managed to find a loose end and asked the shop to cut it for me. I use it for my CDP and Pre-amp with good result, the sound is more 3D and separation of instrument is better and as Kmg hing said, the vocal is mroe stand out.

Will try to get 2 more to put on my power amp and the power filter.

Hi bc,

I have to search for it because last time they only have a loose one which is around 6 inches long and I asked them to cut for me into 2 smaller pieces. I tried 6 hardware shops and only 1 has this pipe lying on the floor, I don't think they actually stock those, but the left over from their construction work or something, anyway will try if they still have.
