如果距離唔係好長(2m內), Lan/fiber fiber/Lan ,有效果嗎? 值得投資嗎?

一定有。

但鍾唔鍾意個效果因人而異。所謂Fibre Box嘅效能同音質亦都受多方因素影響，例如光纖transceiver嘅質量，供電，諧振等等。要有多隻香爐多隻鬼嘅準備，但玩得到你一定唔會後悔你花嘅時間同精力。

Yes...!! 恐怕到時又要開多個 topic 講
連 fiber box 頭關的電壓不同都會影響動態，所以真係一個科學 topic…

我諗過拆咗部 NAS 換鋁壳，機入面摆位重新 layout 過。鋁壳先至可以玩腳玩墊，點都靚過塑膠壳。

不過諗住先，宜加有其他嘢玩住，等到身痕至整。

小弟冇强逼癥，但係週時身痕個度毙呢。

box入面兩個 fiber transceiver 一定要分開兩部 power supply，咁樣先可以彻底隔絕電氣連接。仲有，對 streamer 個部要用 LPS，玩埋大補丸 fuse，同靚 PC。因爲呢部 LPS 的電流波紋會經由網線入 streamer 度，直接影響成套機的聽感，真唔係講笑。

其實難重新layout，底板唔係一塊過，切開晒。sata接口一塊，usb/lan又一塊，接口又唔似係pcie，唔跟內部擺位就多數要用add-on riser，又係多個香爐多隻鬼。都係嗰句，玩得到玩得好，你好嘢，服！

There is a Taiwan C-Fu built an aluminum block for his NAS.

Using LAN isolator and audible noises which can be heard when the NAS is in operation e.g. fan noise, are 2 entirely different matters.

Yes agree... 但我個人唔會太依賴 fuse，因為有 d 大保丸真係好大音染，又或者偏重某方面，要適可而止。

understood the taiwanese C-fu may have confused about the definition of "noise".
my referencing to his post is for his DIY NAS aluminium block case. This looks like a good way to make NAS fanless and absorb much mechanical vibration.  Although this still does not resolve many of synology or most other NAS weakness (lack of isolation, clock, etc), cost to make such aluminium block may not be that high for some reasonable improvement?

Again off-the-shelf NAS itself is not a Hifi equipment, but one can find other solutions to add on an existing one.

師兄可否分享一下現用牌子及過程經歷?
我很有興趣
謝謝

要簡單嘅，Edison嘅Fibre Box就一個箱包晒。

我一直都係用LevelOne嘅GVS-3110，另外有聽過幾百蚊一對嘅淘寶貨，到幾千蚊一隻嘅美國貨，果真一分錢一分貨。高級嘅工業用光纖乙太網裝換器背景噪音甚低。個人建議用single mode光纖嘅轉換器。

電源有用過跟機火牛，Teddy Pardo嘅power supply，Kenneth Lau嘅power supply等。目標都係搵低noise level嘅電源去餵。

LAN線同DC線我就無乜點玩。我用Supra Cat7+，換過一次RJ-45。只可以講，唔好忽略LAN線嘅termination，頭嘅質素同夾頭嘅手工都有影響。

光纖就比較麻煩，因為好難搵到好嘅。如果有師兄搵到不妨單聲。

處理諧振墊釘等等都對音色同重播質素有影響。有試過普通rubber feet，山本黑檀，Ceraball等，最後用symposium啲point pods同ultra padz。

應該用USB音頻線連接NAS和DAC解碼更好，NAS裏面的DSD（DSF，DFF）都可以播放.

呢個係我No. 1原因我個streamer唔係直駁NAS。

如果部DAC系采用XMOS方案，可以讓NAS與DAC通過USB音頻線相連接播放音樂（DSD音源都得）可以用手機或者iPad通過WIFI揀歌，唔使天天開電腦揀歌。

Does this over heat impact sound performance? I'm using HS251 now and would like to change it if needed. Thanks.

Do you have overheating problem now? My experience with HS251 was very positive, no problem with overheating and it never gave me any problem. For total silence operations, I was using a single 1TB Samsung evo850 pro SSD? By the way, I strongly suggest you to use a CH X1 to enhance the performance of your L1 and C1. You will not regret for sure.

From my very limited knowledge, there will be heat-induced noise. But how large the impact to the playback quality, I have no idea.
