at least, i2s makes the DAC option is much more limited than other ports. If really so good sound  ...

I can't see the relationship between the quality i2s and your observations.

這都取決於DAC的價位和DAC廠家的偏好:
1. 到了5萬級別的DAC,USB可以做的很好了。說實話,2010年出品的A ...

I hope you've really compared the i2s and usb input of the same machine.
Marketing doesn't relate to the quality.  In fact, in quite a lot of cases it's against the quality, just for the cost and sales.  
All you've mentioned is only the choices of products, just sounds like an ordinary salesman persuading an ordinary consumer to buy something they don't know.

yes, you could always pursue the extreme sound quality of i2s until there is no i2s DAC anymore.

seems like you really enjoy the hypothetical discussion. This is discussion about 50K DAC, it is useless if there is not much options of i2s DAC in the market. This is real world for practical choice discussion.

USB輸入介面當然可以做得靚聲,USB更加時現時必需要有的輸入介面,除了高規格訊號傳送之外仲可以做埋Firmware upgarde,仲需要配合市場的大量的USB 訊源,USB cable,證明USB 泛用性功能性很高,因此去到50K左右價位DAC,每個品牌的USB輸入介面一定唔會差。

另一方面諗,越來越多的高價器牌的DAC都會使用自家標準傳送介面,例如DCS的dual AES, playback 的Plink,而I2S只是其中一種,因為廠方都會用自家的訊源作配合,以達到廠方認為最理想的聲音質素。如果是使用有這種自家介面,當時優先使用,而沒有用自家介面,廠方基於高規格訊號傳送,USB通常都會做得很優秀。

所以最後選擇DAC 並不應以有沒有I2S輸入介面用最優先考慮因素,應以訊源配合及功能需要作最優先考慮。

Same to you.  Unless there is a table listing ALL the DAC in the market with and without i2s.  Figure doesn't bluff.  
And up till now you only mentioned the hypothetical availability, but not the techinical comparison between i2s and USB to justify your subjective personal preference to USB over i2s.  Again, Figure doesn't bluff.  

Keeping enjoying your "去年買的Ayre Qx5-twenty with USB2 board,USB口就是所有接口中質素最高的".

As you don't know, all these top notch models under DCS, Emmlabs, Bricasti, Weiss, Chord DAC all don't offer i2s.

If i2s is the "best" solution as you say, why these top brands don't offer?

What are the 50K DAC with i2s that you will recommend to beat these above top brands?
