@saurabhgarg Hello!
I have a Tambaqui with the Grimm MU1. This match allows the Grimm to upsample to the Tambaqui using AES. It is my understanding that if you use USB, you bypass the streamers upsampling and allow the DAC to do it, if it does. Using AES output from streamer to DAC bypasses the DAC's upsampling and clock. How are you connected from your N20 to your Tambaqui?
