Now I know   The naming scheme is so confusing.  I thought I'm buying the same one, except it is in silver.

  I just received this one from the mail: https://www.icronshop.com/home/ranger-2304ge-lan- Internal is very different from the RG2304GE-LAN that you link above.        

  Hi Simon,   Do you mind to share the pinout of the PCIe connector?  I bought an U20 w/o USB, so I want to adapt a DIYINHK board to the inside.   Thanks!

I'm going to get some Sylvania JAN 5814A for my WA7tp.  Does it matter to get matched pair or not?

I like the balanced output, it seems to be more spacious.  But in my case, I have balanced connection from the DAC all the way to the headphone.

Anyone with Vega and Taurus MK2 combo needs to turn the volume control very low at normal listening level?  That's the case if I leave Vega vol at 100.  With my LCD-X and Fostex TH600, I can't turn knob pass 9 o'clock.
