I just can't stand PC noise. IMO, it makes sense to have quiet computing if you have nice audio gear, especially with open headphones. People stress about the quality and cleanliness of their sources when they have a loud PC right next to them. That makes no sense. Having a loud computer increases the noise floor of all your audio.
I notice no background noise or anything wrong with my sources. Sounds perfectly fine. I route my gear into an E9 connected to an Xonar DG.
