I did not initially read your post, but my eye caught an obviously malicious post stating that something is a disaster regarding the unit I use (where I'm quite sure person even did not hear nor use the discussed DAC) and stating that a person who developed the mentioned unit has no clue what he's doing.
On another note, I fully agree with you that noise can be found all around and with meticulous approach removed to achieve even better sonics.
And sorry for over emphasizing this noise conversation, but seeing what TAS and the T usb driver did to my systems when I thought they sounded amazing with Roon, has me realizing how much noise can be taken away from a system even when you think it's all gone.
