買呢D 大路USB DAC 試下,唔啱再放出去唔會蝕好多。
https://www.review33.com/2ndhand/forum_message.php?topic=92210123140651
買張 華碩Xonar sound card亦唔貴。
不過 YT聲效好極有限。你用盡方法YT最好聲都可能同 3.5mm output會分別唔大。好多人 desktop聽音樂用 nearfield active monitors。冇冇諗過呢樣玩法?

https://tinyurl.com/xocpoac0 - #27 [phil.ng], 21-02-17 23:41留意下power supply
https://thewelltemperedcomputer.com/Intro/SQ/PSU.htm
“Even if you are using a linear power supply to power the PC, the components are still powered by SMPS.
An alternative is to drive the sound card by a separate PSU to shield it from the dirt going on the power rails of the PC.
Invariably a linear PSU is recommended; a switched one is considered an audiophile crime.”

- #29 [hahayanyan], 21-02-19 11:06back to the topic..
after a few day study..
i tend to believe it is PC USB > XXX > DAC
XXX- may be some sort of DDC...reclocking... a bridge..etc etc ...
XXX may be more than 1 piece of equipment
but what is that XXX .... within different budget level..., i like to find out...
haha - #30 [PhantomGTR], 21-02-19 11:14XXX = isolator + reclocker
我記得有呢樣產品,但一時諗唔起。
如果部 DAC 既 USB input 已經有 isolater (e.g. Rockna),咁 XXX 就只需要考慮 reclocker(只限以PC output 來說,唔太差的 streamer 都不用 reclocker)。

2-channels 大系統 - #32 [hahayanyan], 21-02-19 11:23Does that always make sense to use a Y USB cable for feeding the power externally by a LPS but not take the power from the PC usb?
If it is the case... Is that any not crazing pricing USB Y cable around?
Or better to go for a USB device with their own LPS etc.. But only using the signal Pin from the USB..?

光纖 應該 最唔好聲
但如果拉得長, 佢可能是最好聲 - #34 [alvinlee], 21-02-22 15:53我諗 asynchronous usb dac 係唔係用唔著 reclock,因為佢會用 DAC 自已個 Clock。
https://www.psaudio.com/pauls-posts/myth-asynchronous-dac/ - #35 [老坑], 21-02-22 18:29請教一下,請問乜野係DDC?有乜作用?小弟我啱啱開始玩CAS,但我係PC > DAC > HEADPHONE咁玩,成日見到DDC呢樣野但又唔知係乜,請各師兄指教一下,謝謝。
- #36 [藍晶晶], 21-02-22 20:39DDC 係,將電腦USB 輸出轉成同軸/BNC/IHDMI/光纖去DAC 的一個器具.
- #37 [老坑], 21-02-22 20:46即係digital digital converter? 咁我部dac原生支持usb輸入咪冇需要用?因為我睇返說明書部dac嘅usb輸入先支持最高嘅sampling rate。
- #38 [peter827], 21-02-23 09:33專業人士或者會同你講,用ddc之後唔駛高解像都靚過晒其他訊源。
- #39 [mm452], 21-02-23 14:00其實最簡單係買一套好少少嘅active2.1電腦喇叭就得!

“我工作的電腦接上了一塊 creative sound card cost about hkd1500, RCA output, 聲音正常舒服就像一套質量可以嘅微型音響組合這種聲音, 當然 vs headphone output好了很多很多”
吾用digital volume 去cut volume, 個rca out 可能已是 fixed out, 但要明白每款 sound card 的線路設計
我是想提下如要好聲丶盡量吾用digital volume
