I am sure Roger Sanders does not mind if I quote what he wrote to me regarding the regulator on the Magtech amplifier:"The regulator just holds the voltage constant -- it doesn't change like it does in conventional, unregulated amps. So a graph would just be a straight line."
"You can easily see this for yourself by attaching a volt meter to the amp and playing music or applying a fixed load. The meter won't do anything but sit on 180 volts."
"The same is true of RF energy. The regulator works by only switching the power when the voltage on the rectifiers crosses the zero point. Therefore, there is no switching done under high power/current conditions that causes RF."
"The same is true of the distortion levels. You can hook the amp up to a distortion analyzer and change power levels and the distortion simply doesn't change (it typically sits at 0.002%)."
"The Innersound ESL amp and the Magtech amps use similar (but not identical) amplifier modules. So the amps draw similar power at idle.
However, the Innersound amps used different transistors that required more bias current than the Magtech amp. So the Innersound ESL 300 amps draw about 15 watts at idle (30 watts for a stereo amp), while a Magtech amplifier module draws only 10 watts at idle (20 watts for a stereo amp). So an Innersound ESL amp will feel a little warmer than a Magtech."It might be of some interest to somebody.
