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

80 db is a gain of 10,000. If that gain was applied to a .775 volt waveform the resulting output would be 7750 volts. It will take quite a bit of power supply voltage to avoid clipping that one.

Open loop gain (maximum available gain) and used gain are quite different things.
