Matching amp and preamp imput output impedance?

I have a Forte 4A that has a imput impedance of 47,000 ohm and a Cary AE-3 with output of 560 ohm. Will this combo work together, I have been told tube pre's usually do not match well with Forte or Thresholds. Should the ratio be of the imput impedance be 10X that of the output impedance? Also if these are not matched correctly is the amplifier power being limited? Thanks
