By the way I have some emi noise occasionally when using headphones with my RME adi2 dac and that dac is very well engineered . It happens
I don't mean to be rude, but that's a clear red flag -- since it can be dealt with and they chose not to or didn't do it well. I don't / would not own a piece of dedicated audio gear that didn't account for interference anywhere near this price level.
Maybe I'm being too critical, but I honestly have never faced this issue prior to my current R6 Pro, even with a lot of inexpensive buys. Luckily, it sounds like it's going to be resolved
