- #1 [yooo], 19-09-14 21:42新手請教各C兄,同樣千五元,買光纖線,同軸線,CD機至解碼用,邊條線好聲D?
- #2 [cslo333], 19-09-14 22:17for your reference, normally using with RCA/BNC 同軸線; called CONDUCTOR MATERIAL will change or better sound.
TOSLINK/optical normally using with AV AMP;

through testing that the ideal length,to prevent internal bounce-back reflections from corrupting the signal is 1.5 meters.
最後修改時間: 2019-09-14 23:43:19 - #5 [phil.ng], 19-09-14 23:42Also from google about coax digital cable
Now from what I recall it was recommended to either have very short (<9") or moderately long (3ft+) digital coax cables but nothing in between.
是少過九寸或多過一M

https://www.cnet.com/news/the-audiophiliac-asks-the-experts-do-digital-audio-connections-sound-different/
used my Oppo BD-105 Blu ray player hooked up to an Arcam irDAC digital converter and compared the sound of Toslink and coaxial connections. I used my Magnepan .7 speakers for all of my listening tests.
Starting with AudioQuest Carbon coaxial and AudioQuest Vodka Toslink digital cables, the difference was primarily in clarity. That is, the sound was less transparent and softer with the Toslink cable, and soundstage depth was reduced compared with that of the coaxial cable. The differences in sound quality between AudioQuest Toslink and coaxial cables running between the Oppo player and Arcam DAC were larger than I expected.
I also compared the AudioQuest Vodka Toslink and Carbon coaxial cables with generic, low cost cables. The AudioQuest Toslink cable decisively clobbered the generic cable -- that one constricted and flattened the soundstage and smothered treble "air." The AudioQuest Carbon coaxial cable bested the generic coaxial cable by sounding more vibrant and dynamically alive. The generic coaxial cable sounded rather bland by comparison.

還有,市面上音響用的光纖一般都是塑膠產品,高級產品才用上人造水晶。 - #9 [DYreal], 19-09-15 10:40其實如果講得係發燒友,好多都唔用以上呢兩種介面去聽音樂,除咗AV。
- #10 [254mm], 19-09-15 11:20普通人玩hifi, 用coaxial 駁 dac 已很不錯了,唔係个个都玩得起貴野,玩得起貴野,好多會係富豪,但凡事有兩面, 富豪玩
得貴野,可能只為門面装飾,大把應酬,那有你同我咁得閑,咁奄尖。佢地咪係sales 中的水魚,聽哂sales 老点,又唔緊要,佢地大把錢,怕乜? - #11 [DYreal], 19-09-15 11:30呢個問題都唔關係咪富豪嘅事,因為同軸線個規格已經追唔上DAC。所以如果你仲玩同軸線,噉就算你買咗一部新嘅DAC都浪費咗佢HiRes解碼嗰部分。
一部Notebook同USB線都唔使富豪先買得起,起碼佢對得起部DAC。
不過如果你仲係玩緊一般嘅CD機,噉就冇辦法被逼響呢兩個選擇中揀一個。

- #13 [254mm], 19-09-15 12:11玩 Hi-Fi, 好多塘邊鶴, 亦好多來手, 有乜法子喎?, 楊(羊)生咁多!!
- #14 [孟波], 19-09-15 13:11都要睇埋轉盆質素,我部Technics 1000只有toslink輸出,用同一解碼KO晒手上其他有75ohm RCA digital的轉盆。

- #16 [phil.ng], 19-09-15 16:50買兩條二手比下
不夾即放丶可能吾洗錢有得玩 - #17 [唐吉訶德], 19-09-15 20:34Toslink 很難找得到精品
雖然是塑質,但差別也是頗大的
手上有 monster 及 XLO 的,比 cheap 貨是有差別!
一般 1-2K 的 coaxial cable, 也沒有什麼精品! - #18 [strida], 19-09-15 22:04當然是同軸線,綠音室都用.光纖缐多數用於電視去解碼用,可以長距離轉輸.
- #19 [kk6666], 19-09-16 14:16電轉光,光轉電已經係雙重失真
所以同軸係最直接 - #20 [254mm], 19-09-16 22:12日本仔認為toshlink 好过coaxial, 最主要是断開digital 地迴路,減少干擾,佢地信測試數據多过聽声,有乜法.
