Sorry, I don’t understand the engineering behind this statement. The value of having fewer threads is that the Roon processes get a bigger time slice. I don’t think it has anything to do with electrical noise.
I don’t think any claim has been made for improved SQ due to ROCk. At least, there is no claim for improved SQ with a Nucleus/ROCK combination.
