Hi, first post and new owner of a T2.
Coincidently, I have the same issue of this distorted/cracking sound on mids and highs, when used with the Anthem STR. I am going to test switching the analogue output to LOW, however, what did solve the issue for me was switching from XLR to RCA. Of course the question is, what’s wrong with my XLR outputs?
But as others have said, it’s not the best workaround, as making use of the Anthem room correction (that really does a good job) is necessary for my less than ideal listening room, and the ideal choice is to use the DAC’s on the T2, hence the reason for investing in it.
