Idling losses go from ultra low to ultra low. They are indeed 0.1 W lower.Is there any heat dissipation differences in the implementation of the 1ET6525SA vs the previous 1ET400A and are there any difference in power efficiency using a similar power supply?
Efficiency goes from excellent to excellent.
The ultra low idling losses and the resulting excellent efficiency are indeed a characteristic of all Eigentakt generation that many people seem to ignore. The heat from an Eigentakt based amplifier is mainly caused by the power supply, not by the modules.
