HS1300SS 買左半年左右，右邊耳機開始有細微沙沙聲，同埋聽耐左郁一郁右邊耳機線，右耳會突然有好似被針拮既感覺，係咩料
漏電
買左半年就漏電，咁屎架
巴打部dap都係同期買？定係再之前用開？
我估斷機內線，我之前隻1695都係，漏電>無聲，所以對呢個牌子無好感
講漏左，應該係甩chamber>漏電>無聲
巴打請問點睇天鷹座三代？
了解咗hifiman ef500（上次打手巴介紹），但1516又想加多少少買好啲

呢個價不如比多d買adi2 dac
成萬蚊邊度買有得平啲
同埋我都係用$2-3000耳機 會唔會頭大身細？

如果唔係要玩R2R DAC, ADI-2 個SPEC真係冇得輸
當然就買水貨

買二手更抵玩。carousell有部7千幾
套機貴過headphone好常見
就算你買天鷹座三代都係頭大身細啦
有得試嘅就試咗先，就算買二手都係，有d賣家願意比人試咗先嘅

非常有意思嘅實驗，值得睇曬佢
証明到線聲係有方法度，線聲係frequency domain 以外體現

Feliks Audio 出靜電amp
不過都係勁大部，一定好貴
Mytek想出膽機？

呢張係代表咩？
唔識
估應該係唔畀SIGNAL 條線, 去度條線PICK UP到幾多BACKGROUND NOISE (應該係掛)
)我嗰部經常被呢個價位嘅機抽插
如果係咁，我係咪可以理解成條線阻抗低
？
？呢張圖係我手邊有嘅supra dac x線意外發現比其他牌子有較大唔同
另外一條chord cable就好似冇咁大起落

We measure noise the same way we measure interlinks. So with a connection between the function generator and the scope, without putting a signal active. You are now basically simulating a system that’s sitting idle. We didn’t send a sine wave through it this time, because we end up seeing the most in the pattern without any signal running through the cable anyway.
What we have noticed is that the ‘silence’ is audible in the listening tests and mostly visible in the green line (the actual signal). The blue ‘blur’ doesn’t really appear to be audible….
Probably because it is too random and is so low in level that it is no longer audible to us. At least not in our test system.
似係insulation / wire twist 的分別
但真係咁樣度 noise?

你quote 個篇係度speaker cable，我個篇係度 RCA
speaker cable 多數係冇shielding

我諗緊個noise大係咪來自部機度？
係線嘅導體導電率高嘅話咪應該容易有，即使佢冇放signal出嚟，佢冇電過又點可能測試到
？
所以我先諗我放幅圖係咪阻抗低

有兩個角度
1. 部amp 出嘅noise會係呢個test setup 嘅誤差
2. 個誤差係固定，咁唔同線測出嚟結果有明顯分別就足夠代表每條線自己反應
冇電過都測到noise係合理，因為電線本身就有天線特性。收signal 嘅天線係唔洗通電先收到 signal。要電個part 係signal amp。
佢想測個noise係條線係環境收到幾多noise

巴打可否井多少少
想搞清楚d 關係
想搞清楚d 關係咁呢個圖係咪越幼代表越好？
