Not so far. The highest voltage yet attained for current electricity is 5 million volts: The highest electrical potential ever produced by man, over 5,000,000 volts, has been achieved in the laboratory of Dr. Gregory Breit and Dr. M.A. Tuve at the Department of Terrestrial Magnetism of the Carnegie Institution of Washington.
The maximum measured output impedance was 0.16 ohms, at 20kHz into a 4 ohm load, this decreasing to less than 0.1 ohm at 1kHz. This is not unusually low for a solid-state amplifier, but low enough that any effect on the amplifier's frequency response with a real load will be small.
