Hi Do you know how to remove the AMP card once it is installed? I am pressing down the small clamp on the side bit is not working.
You should press card until a click to install it.
Then press to move metallic holder and a card must go up and be like 45 degrees to your dap

It should hold your amp card in horizontal position. After you shift it (?just make sure that it’s not over the amp)- it won’t hold the card anymore and it will go up and after that you can extract it

Is the 901R better than the 901S in sound performance?

warning - outputs on a balanced card with non-zero resistance, so headphones with a non-linear impedance change their tone a lot, for example, with monarch mk2 the sound is simply terrible - there are no high ones at all
