I can’t seem to find an answer online anywhere but what’s jumper 7 on the Argon Eon board?
I wondered this right away after receiving mine. I suspect it is (or was) intended for an add-on, probably something like a Hi-Fi DAC board. notice the two RCA-jack shaped cut-out holes in the back panel? Or the internal mounting point at the lower-left of your picture… just an aluminum post with a hole at the top for no reason whatsoever… Yeah. I really wish they would release such an upgrade. I can’t even find the version of the Argon One case that they used to make with a HiFi DAC in it.
