I have a grimm audio MU2, which I used as a roon core , when I use the MU2 as a core and a streamer with its built in dac the music comes through perfectly. But if I use the MU2 as a core and then play it via roon through my other 2 streamers there is a slight crackle and distortion which I hear from the tweeter . Can you please guide me on the solution
Describe your network setup
The network has a fibre optic cable with a Ruckus network switch which is connected via fibre optics to a Nordost switch from which it is connected to the Grimm MU2.
