I went to a Threshold demo many years ago and the rep had hooked up a Threshold FET 10e to small speakers to demonstrate the robustness of their separate power supply.
This particular preamp had a very low output impedance and put out a few watts of class A power into the speaker load at 8 ohms instead of the typical amp loak of 50 k ohms.
