Switching to DSD512 or PCM 768 requires 25Mb of bandwidth, which should not be a concern.
As we have already mentioned, iFi audio has made a product that is a Swiss army knife and inevitably has limitations when it comes to responding to so many features.
I posted here (NAA thread), it is still possible to go further on the exclusive mode but what is the point for iFi audio to answer to some audiophile geeks.
Most requests are: I plug into my dac (iFi audio) and stream Tidal with my phone.
DSD 512 is not a necessity but it is frustrating to end up with DSD128 because you are going through dop.
And the same goes for PCM, 768 should be the “norm”.
Even iFi Audio is getting there with the Gryphon… they may move but they still haven’t answered the hardware question.
Is it possible to upgrade the kernel to a recent version and open it to PCM 768 / DSD 512 / dop 256.
No clear answer: “possible but not a priority”, “possible for July”… to be continued.
