Since you are running balanced lines, I can introduce another variable. You will notice that your XLR plugs have three pins. These are positive, negative and ground. In some electronics you will have a ground 2 pin and in others it will be the 3 pin. If your Rowland and your Benchmark do not have the same configuration, you will reverse phase by connecting them.
Personally I think you should be glad you are not sensitive to phase. If you train yourself to identify phase anomalies, you will be driven crazy for the rest of your audio life.
