Those who loudly voice their opinions here without personally testing whether there’s any difference, and then think they know all the facts, is really quite funny
@pinkbomb6862 i would say they are very interesting. Is like talking to a person who says there is no difference between two diffrrent wine, as he said the substance inside is the same and never had a chance tk taste them.

今時今日玩Hifi, 最有建設係先去讀個data communication 嘅course，學下digital data transmission 嘅原理，增長知識之餘重會慳好多時間好多錢

今時今日仲覺得010101係唯一影響聲音既原因先好笑。
如果是layer 2 switch，broadcast packet都會有影響。
工業用左好多年, N 年前用 CobraNet
依家就 Dante, AES67
中間 Network 行 fibre,
一來長距離傳輸, 二來解決左電引致既干擾, Grounding 問題, etc
btw, 而家大部份光纖入屋, 已經避免左外部既干擾
再加多份光隔, 主要係隔埋自己屋企內部既網絡干擾
屋企內部既網絡干擾, 個個人唔同
所以會有咁多 subjective 既聽感
👍🙏國仁加油
謝謝chung兄
個人玩法及心得...之前都試過一大堆野攪套cas,最後用utp lan/單邊浮地既網線攪掂,攪好供電最重要..

有冇機會試埋部dac 😄
支持，又可以學嘢
出呢條片其實要有晒心理準備，有產品支持才決心去拍，也因此之前一路都沒有獨立拍光隔的影片（國仁）
講真如果你認為lan線有幹擾
咁點解最尾由switch出去嗰條線行lan線呢
可能我表達不清楚，影片不是指 lan 線有干擾，而是來自使用開關供電無線路由器的干擾經 lan 線導入串流機內
轉介質最多是沒損失，而且好難，合理是雙或者三交換機，Lan轉Lan其實都是有隔離，摩時鐘同供電就可以啦
無獨門技術之餘，定價進取到殺一個算一個…所以hifi點解會沒落？
其實做得好，就已經係一種技術。你問下日本職人整個烏冬又咩獨門技術？ 無，大家都識整。點解要排隊都要去食？ 就係佢整得好。講到天花龍鳳都無用，做得唔好，最後唔好聲 都唔會有人埋單。
@@lscangus要做好音質，各方面配合好重要，部機冇獨特處，市場定位又高，誰買？拆機睇零件最實際

1條50米生銹水喉，換咗中間10米，可以改善水質嗎？
不可以，但生銹水管在飲用前經過濾水器，則幫助很大
點都好過50 米全生鏽？
@@feverSoundHK 既然不可以，咁用濾水器（signal purifier)得啦， 換水喉（LAN Cable 轉光籤）有乜用？講真，有線數碼訊號係純正嘅，中間冇device 將D "noise" digitalized 去一并傳送的。
光電轉換目的正正就是隔掉電氣干擾，光纖是絕緣的
對於一個有雙CCIE 既HIFI友來講，可以話呢部野99.999%係一部搵笨垃圾🤔絕對智商稅
既然你自稱係 HiFi 友，套機始終都係自己耳仔聽，不如自己買件最平嘅試下，科學都講求實驗，用平常心去試，試咗無分別最少都係實踐過，一個銀仔唔係公就係字，但可能有 0.0001% 企中間呢
其實ching 買兩隻平嘅switch 都會有分別。我由隻 HP 換左隻 UBNT 我都覺得唔同聲。

不太明白，請問用一部konNET-k是如何做到光隔的？Thanks!
同用media converter+光纖代替銅LAN線嘅原理一樣
如果不是串流機有SFP輸入的話，我們是需要配置有SFP的Switch或另置一部RJ45SFP的轉換器的🙏🏻
@@feverSoundHK 收到，明白👍
請教是用上那一款SFP，和電源線
沒有去研究，所以無乜意見俾到你
EXD正是改變我音響歷程的轉捩點
當年就是玩Exd 轉換器用在舊款DCS解碼
令我毒死
當時真的沒有電腦音頻轉 SDIF 的 DDC，但 exD 卻做到了

You're simply shifting noise from transmission process to the conversion process, that happens twice.

唔怪得知國仁話呢d產品惹火.. 原來真係好多好多人聽都未聽過就亂噏或者否定佢嘅效果…🤭😂
我唔明點解有啲人反應咁大，又冇人話要傾家蕩產咁去買 😂。呢個世界大把人用難以想像嘅金錢去買舊毫實用價值嘅「所謂」藝術品返屋企擺都係咁啦….
我以前都唔認為LAN 線會影響聲音，之後純粹好奇換咗條千零蚊嘅LAN線試過又真係有分別，而家正考慮買光隔 / Switch 玩下。換咗 Lan 之後唔係天淵之別，但係的確係有明顯嘅改進。千零蚊對我剛好，再貴嘅我就唔會了。
數碼傳輸係極高密度的 1/0 組合脈沖電流或電波。少量干擾或流失對整體的確冇咩大影響，數碼系統亦會以既定的 Parameters自行識別或修正。
要視乎系統的敏感性及訊號的複雜度及密度吧，就等於MP3同Hi Res 對比。當失真或流失有一定嘅時候就一定會有分別。網絡電話都係數碼傳輸，訊號差嘅時候都會窒窒吓啦….
揾條dela dac cable 取代光纖線！ 應該會有可聞嘅分別

照道理用WIFI 隔仲好聲 整部RJ45 入 RJ45 出 , 中間係WIFI (靚電版MESH) 俾個「氣隔」名稱佢..仲唔肥肥
理性地說，WiFi 本身就係一個干擾
@@feverSoundHK 照道理一個屋企唔會冇WIFI, 善用WIFI 相信比LAN 線產生對線路干擾更低
但安裝 wifi 發射接收器在器材內呵，干擾不是比一般室內大很多嗎？如果要隔絕干擾，可能要雙重金屬屏蔽
@@feverSoundHK 如果你話LAN線會帶入電流操音, Wifi 產生最多都係EMI/RF 干擾 , 同電流產生干擾真係蚊髀同牛髀啦
其實係可以
但Wi-Fi嘅不足係穩定性
同埋會有 latency
