[#1] XLR to Din 入SN2 Naim forum 話balanced to balanced; unbalanced to unbalanced, XLR to Din 根本無意義。 因為我部LKS 004 當然唔會有DIN output,我就淘左條人仔600 XLR to Din。前後試過兩對過千元RCA,發覺我條淘記XLR to Din 無論在動態、底噪、細節...等等都高一班,係一開聲已經聽到分別果種。 而家睇緊英國d RCA to Din,諗緊訂一條試下。 大家點睇? Chord 有條Din to XLR,反轉用又得唔得呢?多謝! 最後修改時間: 2020-12-10 07:26:38 |

[#2] XLR to Din 入SN2 你看的forum 可能吾夠深入⋯⋯ So why do Naim prefer to use DIN connectors? The obvious reason: DIN connections sound better than RCAs… The phono plug, or RCA connector, as best as anyone can remember, was designed decades ago as a direct current (DC) power connector. Its design properties do not lend themselves to transferring music signals that have very low voltages (less Than 5 volts) of alternating current (AC). This is true - no matter how good the RCA plug is or whether it is made with gold, etc. The first difficulty with the RCA connector is that it has a high-frequency capacitive impedance of around 200 ohms; unfortunately, the typical cable that connects the two RCA plugs together has an impedance of about 50 ohms. In this situation, the two RCA connectors on either end of the cable act as reflective walls at higher frequencies and bounce information back and forth, trapping the signal and extending the decay time of the signal that is trying to pass from one component to the other. These reflections have an effect on musical information and are especially harmful to low-level signals, particularly quiet harmonics and underlying instruments, where the ringing that is generated by the loudest instruments will smear the smallest signals. The result is that the quiet instruments will blur or fade away when the loud ones come along. The complexities of the music and the tones of individual instruments get lost. The DIN plug has an impedance that is similar to the cable. It does not reflect like an RCA plug. Furthermore, the system ground (which should be a stable connection point to which all signals and power supplies are referenced) is absolutely critical to the sonic performance of your hi-fi. A single reference ground point is important so that signal details are not lost in the small, yet significant voltage differences inevitable with separated ground paths. Many manufacturers point to the great trouble they take to “star ground” everything. Sadly, this is all wasted when you connect your system together with RCA-plugged cables. Why? When you connect, for instance, a CD player to a preamp with RCA-plugged cable, you automatically have two separate ground wires - the left and right shields going between them. This creates a ground loop, which degrades the musical performance dramatically, and negates any efforts that were taken to ground the internal circuits properly. If you were to connect these same two components together with DIN-plugged Naim interconnects, you would have only ONE cable with only ONE ground shield surrounding both the left and right signal wires. Hence, only one ground path for each connection and no ground loop. |

[#3] XLR to Din 入SN2 Chord 有條Din to XLR,反轉用又得唔得呢?多謝 ............... 為什麼不試丶又不會燒機丶xlr 不同rca 通常兩邊都接shielding丶不同rca, 好多種接法 |

[#4] XLR to Din 入SN2 多謝Phil 兄詳細分析! 我知道DIN 係比RCA 好,對Naim 機黎講,如果無辦法DIN to DIN,我的經驗係 XLR to DIN 會有驚喜。 拋磚引玉。 |

[#5] XLR to Din 入SN2 重點是din左右聲道同一plug, 即是左右ground 只接去一點丶沒有ground loop 問題 留意此 When you connect, for instance, a CD player to a preamp with RCA-plugged cable, you automatically have two separate ground wires - the left and right shields going between them. This creates a ground loop, which degrades the musical performance dramatically, and negates any efforts that were taken to ground the internal circuits properly. Xlr 也要行兩條線丶即是仍有以上問題 最後修改時間: 2020-12-10 10:20:02 |
