RCA outputs on the back panel are 100 ohms impedance. Nobody runs headphones off those.Fun stuff, with RME if you have high impedance headphones, use xlr. I a/b RCA VS XLR (to SA-1) with my ADX5000 and there is a difference in low end, slightly more dynamic presentation. Midrange and treble showd no difference and initially i tought that there is no difference. RCA has 100Ω impedance and XLR has 200Ω so there might be the reason for mor energy in the low end. I dont believe that this is due to cable quality and if both were 150Ω i dont think there would be a difference.
The headphone jack is 0.1 ohms impedance,
