@vanlaren Hi, with Arylic products you can use their ‘APC Workbench’ software to control the output (incl. signal strength) of the Arylic device. Here’s the info link. Be aware that this software runs on Windows only.
This would be ideal, but unfortunately APC Workbench is not compatible with the Upstream HD DAC.
For now, I’m keeping the EQ at -12 db. Fortunately, this setting is not forgotten after a reboot.
Thanks for the feedback everyone!
