我 Roon server 上有 onboard dual lan 試過直去 NB, 效果好壞參半. 這 fanless 類似 NUC 的小電腦, 無 PCI ...

I also use Stillpoints Ultra for my speakers. It improves quite a lot particularly in the aspect of soundstage.

Yes thanks, I saw this in their forum before.

Jcat Net Card昨天已經收到，沒接外部供電。實驗從pcie接口取電和pc電源內部4p口供電，效果差別不大。
說重點，串流播放改善之大，超乎預料。聲場的寬度和深度有明顯改善，層次感很好，樂器分布前後左右錯落有致，有很強的立體感，聲音密度提高，更顯圓潤、安定、凝聚，質感更加強烈。
壹個小小的網卡，超值！
小弟系統是pc，操作系統win10，播放軟件roon+tidal+hqplayer，melco gs2016交換機。解碼total six+reclocker，atc sca2前級+scm50aslt。
據說用uptone線性電源供電，效果更進壹步。長草中。

I follow JCAT's instruction to configure the network adapter settings except the followings:

Jumbo Packet : 4088 Bytes
Maximun number of RSS Processors: 2
Maximun number of RSS Queues: 2

The sound is more natural in my system.

跟JCAT較RSS去到8似乎會太厚同有D古怪？
另外收發buffer 80好似都會變厚？

If RSS and Buffer are set as 2 and 80 respectively, the sound is more nature in my system.

這個JCAT Net Card Femto x UpTone JS-2 LPS x Roon x Tidal組合, 確實令人難以置信。

"....這個JCAT Net Card Femto x UpTone JS-2 LPS x Roon x Tidal組合, 確實令人難以置信。" Totally agree!

Addition of PACHANKO "Pure Reference" SATA cable to my Roon sytem is probably another huge improvement.

PACHANKO "Pure Reference" SATA cable is on it's way from La Reunion to Hong Kong........

加持Uptone JS-2，聲音並沒有出現厚潤的情況。Jcat Net Card Femto主要是擴展了音場的寬度和深度，層次感改善多多；而JS-2則像是給音像做了銳化一般，把樂器的形體勾勒的更加鮮明，質感上也有提高。相比未加載JS-2，聲音耐聽度要差一點，有點扎耳朵的感覺。剛開機的聽感是這樣。期待煲機后會有所改善。

剛剛看到，居然降價了，我買了才兩天，居然降了200塊。偶傷心！偶難過！偶還在這裡吹牛逼，心情寡淡頓時滿滿的數碼味生無可戀了。http://www.headphoneclub.com/thread-723766-1-1.html

請教師兄，JS-2菊部有個sense接口，還附有一根線。這是幹什麼用的？

It is only used for Mac mini DC-Conversion / Linear Fan Controller Kit (MMK).

Quote from Uptone web site :

"The MMK also has a coaxial/SMA jack for connection of a cable to support the pseudo-Kelvin-sense feedback circuit of the UpTone Audio JS-2 choke-filtered LPS. That circuit eliminates the voltage drop of the DC supply cable and ensures instantaneous voltage regulation right at the computer end regardless of spikes in current demand. [Use of this feature is entirely optional, and the computer and board will function perfectly with a JS-2 or any other quality external DC supply even when nothing is connected to the SMA jack."
