Sensitivity of MKIII Poseidon boards

[Prima Negev]

This may have been asked before but I did a search and did not find the answer - are the Poseidon boards sensitive enough (produce enough gain) to be used with a passive preamp?

NO! You will need some gain to appreciate the power output the amps are capable of. It will however work with a passive preamp but with less power output. The MK IIIs are for those who wan,t the power output they are capable of. If you are into low power output and have sensitive speakers, you should be ok.

Thanks for the answer but I am really seeking the actual sensitivity of the MKIII with this driver board installed. I know the VTA board is far more sensitive (perhaps a bit too much). I seek a figure such as 1 volt to drive the amp to full output etc. I am using a passive pre but it is transformer based and has 6 db gain.
