@lordmelton thank you.
My future purchase will depend on how long I can wait for the Phoenix to appear on Hifishark :). If it is too long I will go the DDC way.
It would be very interesting to know how SOtM USB performs in comparison to the I2S after a week.
I noticed that the DDC you listed doesn't have a reclocker. The I2S interface will transmits the clock with the data to the DAC. The DAC could then benefit from being driven by a better clock improving performance.
