Input impedance of the Odyssey Stratos Dual Mono

With the dual mono at 10K at input and the following for my ARC SP16L, is this a mismatch? Can the ARC be tweaked to get into the right range? I understand that the ratio should be 1:10 (preamp to amp) for optimum performance and lowest noise. Thanks.

ARC SP16L OUTPUT IMPEDANCE: 260 ohms Single Ended main; 20K ohms minimum load and 1000 pF maximum capacitance. Outputs (3): 2 main, 1 record (Single Ended RCA connectors
