What I mean is one says it, then another and another.
It’s an unwritten law the output to input ratio should be 1:10 or better eg: 1:100
Not many look at the specs to see if the ratio of what the RME output impedance is (100ohm), and if it 10 x less or more than the input impedance of the power amp it sees, in this case the Rogue at 100kohm! so 1000 x less, so absolutely problem at all.
