Compatibility between preamp and amps

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.  

Good answer.

thanks but isnt there more to it than impedance ratios? like gain and sensitivity?
