There is another important spec which is not mentioned in their website. Since a separate power amplifier is involved here, the input impedance of the power amplifier should have been mentioned, but is not mentioned, only the sensitivity in volts is mentioned, i.e., 1V. An idea of it's input impedance is very important, incase one would like to pair another pre amp to it. It would be nice if anyone can shed some idea on this.
Thanks
