The Gaia also offers more inputs (AES/SPDIF/COAX), as the Iris only offers to reclock and convert USB. If using a Terminator +, you can use that clock to sync up the Iris as well.
New Denafrips recklocker/converters: IRIS and GAIA
Denefrips recently announced new products that recklock and convert DSD and PCM.
IRIS - $472:
---------------
Input: USB
Output: I2s-HDMI, I2s-RJ45, Coax, AES and Toslink
GAIA - $1604
-----------------
Input: Coax, Toslink, AES, USB
Output: I2s-HDMI, I2s-RJ45, Coax, AES x 2, Toslink
Both have connections to add external clocks.
Might be worth looking into if you have a DAC that has I2s, (or another input) that your streamer does not output that you'd like to try. Available for pre-order. I might have the prices wrong, as I tried to convert from Singapore dollars.
