Bump.
This SU-1 is killer.  I had no issues sending a 352.8 Khz from a Windows 7 computer to my DAC.  There are dip switches to select the I2S HDMI pinout for your DAC.  I have mine set now for a Wyred 4 Sound / PS Audio i2S input.  The Kitsune has upgraded parts and a linear power supply internal in the case.  
My initial photos showed dust that I did not wipe off so I attached better photos.  I also captured a sharp edge where I cannot tell if it is powder coated.   
I am willing to accept Paypal Goods and Services payment of the buyer pays the 3.49 percent fee.
