So, I was thinking about getting a Denafrips Iris DDC to do the reclocking job, but haven’t made any firm decisions yet.
I bought a Denafrips Hermes a couple of months ago for the similar reason, plus to try converting USB out of my streamer to AES/EBU that I could input into my DAC. The Hermes and Gaia offer more options for clocking, particularly if you have a Denafrips DAC, but my first step was to try it as a converter and hopefully send a lower jitter signal to my DAC.
Regarding the sound, it seems to sound at least as good as running a USB direct from my server to my DAC. This may say more about my server and DAC since they have quite high quality USB interface boards. At the least, I can say putting the Hermes in the chain does no harm sonically but, again, I did not even use the clock function so there is probably considerably more potential to be had.
