Lumin T2 mid/high distortion "spitting" "splatty" DAC gone bad?

I used the D2v with ARC but now I have the Classe Pre in the mix, I’m going to do my 2 channel room and speaker correction using a convolution filter in Roon. I’ve already started engaging with Mitch at Accurate Sound. Really looking forward to the process. https://accuratesound.ca
