Thank you for pointing out that search bar. I use dark mode on my browser and that bar was hidden a bit.Just an FYI, you can use the search bar at the top of the page to "search" this thread / research a general question. There is a lot of helpful information on Headphone mode.
What headphone(s) and DAC are you using?
I have a SMSL SU-9n for my DAC and a pair of Audeze LCD-5 and ZMF Verites as my main headphones. I've been using them with medium gain in headphone power amp mode the past couple days.
