HQP NAA - Raspberry Pi

[volpone]

Could you confirm or correct my understanding about DoP / Native DSD bitrate ?

My bad !
Sorry, answers were already on this thread:

If you are using NAA, then DoP vs native doesn’t make difference in bandwidth consomption. DoP is handled at the NAA side, so there’s no wasted bandwidth to send DoP stuff over the network.

So DoP X2 bandwidth consomption is on USB, not on Ethernet !
Seems ROONBRIDGE act as HQP NAA. DoP handled at the endpoint side.
