90 db of gain on a .775 volt source will clip very badly. 1 mv will be amplified well over 10,000 times and will also clip.
I don't think I follow you. Why would 90 dB of gain on a .775V source clip badly? Available gain should be a function of PS voltage. The PS of the KGB runs at +/- 24 VDC. Is that not adequate?

The test spec given on the A-Designs site is 2kHz, btw.
