這類 Marketing Campaign 營運手法，在鬼佬世界可能受落。 愚見是扭得太盡有過火之嫌，我真的不得不認老了。

Hercules and Chaucer hing,

路過。。。提一句, 有機會問LH 取 HDMI I2S 的 Pin assignment .  

其實I2S/HDMI 的 pin assignment 也幾多樣化, 不同品牌有時不一定talk得到.... something may be partially works like Rockna and LKS Audio..... (PCM Only). 有時完全不同pin ....., 所以最好問一下.

Cheers,
Blau

Yes, for example, Rockna needs 5V in pin 18 to detect the incoming signal.  Wyred4Sound does not need 5v on pin 18.  These minor difference need to be considered to make I2S over HDMI works for different devices.

Dear Chaucer,
Please ask Larry via the Geek Source Indiegogo webpage the HDMI pin asignment and details as mentioned by Odyssey Audio.
Many thanks!

Thanks for Odyssey & CKKeung remind me of this. Just ask via Indiegogo. Let see what happen. I'll voice out again if it happens not Rockna compatiable.
BTW, Rockna compatiable spec at "source" is not harmful to PS Audio, W4sound DAC performance , is it?

I may not understand 100% your question.  Both pin assignment and signal compatibility are important.  Also, DSD direct streaming over I2S is something amazing.  You may also check if it is supported as well.

The +5V on pin 18 detection is required by Rockna and Audiobyte DAC as designed. Wyred4Sound prefer not to use +5V as he want to make the I2S interface galvanic isolation and have better sound. (New MS2 with Femto Clock implemented galvanic isolation on I2S).   So W4S DAC detect signal transmission instead of detecting the +5V at pin 18 to optimize for performance.

To make W4S Music Server compatible to Rockna DAC, we have requested W4S to offer option adding a switch at the back of MS2 to choose between the 2 I2S output modes.  

Hope it helps.

Well noted and thanks.

In a scenario where I2S pin assignment is as PS Audio/W4S  at receiver side (DAC)and is as Rockna at source side respectively, adverse sonic impact should be insignificant IMHO because the receiver side pin 18 is simply not connected.

In order words, it is advisable Geek Source using Rockna/Audiobyte pin assignment since
1) no matter the DAC is a PS Audio,W4S, Rockna or a Audiobyte, Geek Source works.
2) no adverse sonic impact to PS Audio/W4S DAC.

You are right that W4S DAC2 I2S does not use pin 18 5V anyway.  So electrically you are right .  

There is difference with cable, like usb cable whether you want the 5v presence or not.  If the Dac do not need the 5v, some Ching find it better to cut the 5v connection from source end .  I don't know how significant it is in this case.

When u receive it , welcome come and compare. Cheers .

Hi Hercules,

你和 LH Lab 較熟，請你在 Geek Source 網頁的 comment section 問一問以下問題：

$109 USD
3rd Femto Clock for USB 3.0 Change Perk
By this perk, you will upgrade the 3rd dedicated TCXO clocks to femto level for USB 3.0 audio output port. Lower the jitter of audio signal output in USB 3.0 is one of the most effective way to make your music sound "Real". With this perk, we will put the associated "Super Quiet Clock Power" circuit there too. So your femto clocks get its dedicated shunt regulated power supply lower than 5uV noise. Best power for the best clocks. No compromise here!
