Higuma 兄您好，基本上就是 Thesycon 與 XMOS 雙方提供的（3rd-party）ASIO driver，理論上 Windows 10 和 Server 2019 等等的平台也合用，因此相當肯定不會是 UAC 2 那種只可以支援 WASAPI 的 in-box USB Audio 2.0 driver：作者: Higuma

畢竟原生的 usbaudio2.sys 大概是沒有提供甚麼選項的說。
對了，實際上的功用就是令樹莓派變成另一台 PC／樹莓派的 USB 音效卡，如果要優化 USB audio driver 的話大概是需要修改一些 source code：

早於 2015 年，當時的樹莓派 Zero 也支援 OTG 了：

另外 IanCanada 的 ReceiverPi 和 HiFiBerry 的 Digi+ I/O 也可以令樹莓派變成其他介面的音效卡：

這個就比較難猜測，小弟聽說 ASIO driver 和 TAS 等等軟件好像是由荷蘭當地的一位台灣人 Edward Hsu 和他一眾隊友共同開發的，但是據稱那 Thesycon／XMOS ASIO driver 只能夠配合 TAS 一起使用才能發揮應有的水準云云，創辦 WBF 論壇的 Steve Williams 把他的 DAC 送回 Lampizator 原廠那邊升級，他們把原有的 Amanero USB 介面更換為相對新款的 XMOS XU-208：

後來廠商剛剛把 DAC 送回給他，初時 Windows 10 LTSC 尚未安裝那個客製的 ASIO driver，因此硬件升級後也好像是顯得沒有甚麼分別，可是 Taiko Audio 的老闆 Emile Bok 完成了客製 ASIO driver 和 TAS 測試版兩者的安裝之後就令他大喊 WTF 了：

那一位老闆於 2008 的時候已經開始鑽研 CAT 了：

人外有人，天外有天，當然這個世界就是一山還有一山高，不論 Taiko Audio 如何窮一生的精力去優化各種軟件和硬件也只能夠受制於 x86 這種平台的（先天性）短板，理論上是十分難／不可能超越西班牙 WADAX 最新的旗艦產品：

比『變態級』更變態的光纖線：

就算是再強的 Xeon CPUs 配上功力多麼深厚的 Windows／Linux 程序猿，技術上也不會那麼容易超越 WADAX 研發的那一種 ASICs（Application Specific Integrated Circuits）。
前者純屬一般的 general-purpose operating systems，根本上就不可以跟後者同日而語：
https://www.whatsbestforum.com/threa...-2#post-689210I hear that Wadax Reference Server does not depend on computer industry soft and hardware. It still use Roon but will be enhanced with their custom extensions. The most important is that it will use the proprietary connection interface which is only compatible with their Reference DAC.
畢竟 WADAX 的僱員數目大約為 400 名，Atlantis Reference DAC 的售價已經逼近十五萬鎂，加上旗艦 Atlantis Reference Server 的一套系統應該是差不多三十萬鎂了，不知道僅僅 CAT + DAC 就超過八百萬的聲音將會是甚麼景況呢？
那種『可怕』的系統能夠瞞天過海，播放 TIDAL 數位串流音樂的時候足以令所有在場的發燒友受騙了，誤以為當時播放了大約三十分鐘的聲音是來自黑膠唱片：

https://www.audioexotics.com/product...reference_dac/原有的 CDT Six 和 The Fifth Element（九萬六千英鎊 + 九萬六千英鎊）兩者實屬異次元的東西，再加上整套 Siltech Triple Crown 的線材就不知道怎麼形容了，然而 WADAX 實在是魅力沒法擋，看過這些 Audio Note 的評測後就可以猜想 WADAX 到底有多可怕了：The biggest shock comes from Lincoln Cheng of Audiotechnique. Lincoln, who is a big fan of Audio Note UK decided to sell the ANUK flagship CD/DAC system in exchange for the Wadax Atlantis Reference DAC/Transport. He even had to modify his rack in order to house the big Wadax DAC. Why would he go through such hassles under a COVID environment?

The best DAC I ever heard work with 44 KHz use a old AD1865N with 18 Bit.
Which one? A AudioNote Fifth Element. Forget your GG or very other DAC.https://www.whatsbestforum.com/threa...-3#post-318118One of the best I ever heard was the AudioNote Fifth Element DAC.
I never heard the Fith Element as a Stand Alone DAC. So I don´t know how it sound. I heard a complete Level 5/6 Chain from AN.
Very close to Live Music. You listen only to the music, not to bass not to middle not to highs. I can only tell you that the DAC has the same Quality as the AN TT3 with IO Ltd Cartridge.I have the 5th Element in my system with the CDT Six, this kit offer the most relaxing and involved Red Book I've ever heard. It's like playing records. I am getting zero digital hardness.
