Expert 1000 Pro

[Confused]

I wonder if the increased temperature applies only to the class A amp or the entire device. Maybe running  the class A part hotter makes it more linear and still could reduce the powerconsumption of the entire amp.

To summarise from my earlier post, on the same (very hot!) day, with the same speakers, very similar volume, the D800 was running A=43° D=42° S=41°, the Pro was reading A=57° D=48° S=50°.  That does not look more efficient to me.  It did sound good though!
