Compatibility between preamp and amps


As I am researching preamps and amplifiers I have been reading that gain/impedance/sensitivity can affect how well the 2 components get along. Take for example Modwright LS100 and Wells Audio Innamorata
LS100: Gain 11db, Input Impedance 38K, Output Imp 300 OhmInnamorata: Gain 30db, Sensitivity 0.85V RMS, Input Imp 30K

Based on the specs does this like it would present any potential issues?
Thanks

Output impedance of preamp to input impedance of amplifier is the biggest concern.  There is a minimum ratio that plays well together.  

I have an Aesthetix Calypso with 1000 ohm output impedance which was not enough to make the Edge M8m amp with 30K input impedance happy.  That is 1:30 ratio.  It liked the 300 ohm output impedance of an Acoustic Research LS17SE much better at 1:100 ratio.

The equipment you noted above has the same 1:100 ratio which, on paper, should be an adequate mix.
