*High Current Amp: Yamaha claims its their advantage but this method is quite common
and most of all HiFi Receiver does this! Actually they are following our “Direct Energy
Concept” which we have been using for nearly 10 years!
**Pioneer’s Linear temperature Compensation Design is the most advanced version for
discrete power amplifier design for minimized the variation of idle current which causes
deterioration of the sound.
(Denon uses same power device as Pioneer ,but Denon doesn’t take care temperature compensation
of whole power amplifier desigen)

Speaker drive current cause
temperature rise of output element,

The temperature compensating
block of the bias circuit is made
on output element chip same
as ADE-MOSFET, that’s why it
can minimized the operation
point drift of the bias circuit by
the chip temperature variation.
