Impedance Mismatch: A.I. M3A, Krell KSA100

I've read opposing views elsewhere on whether there is a sound degrading impedance mismatch between the Audible Illusions M3A preamp, with an output impedance of 1.2 K and the Krell KSA100 power amp, with an input impedance of 22 K.

Something tells me that there is a definitive answer out there.

I own a KSA100 and I'm considering the M3A for use with that amp.

Thanks in advance for any first hand experience or expert advice!
