Trigger cable lowers temperatures & power consumption

[G51]

Given the work Manoet and others have done to reduce temperatures for better sound quality I thought I should start a thread about the far easier method of connecting the 3.5mm trigger cable between master and slave units then enabling an input on the slave unit. This simple configuration tweak reduced temperatures of my D400 and equalized the temperatures of the master and slave unit. I assume this is an effect of the lower power consumption when the units can communicate through the trigger cable.

Could you describe or show a photo of the connexions ? I would like to try, but i don't see.
Do you hear a SQ improvement ?
Thank's

See Trigger In/Out on each unit - The cable is supplied when one purchases a set ( i.e. D400)

I own a D200 (master) now. Will the trigger cable come, apart from the Crystal digital cable, with a Slave D200 unit? If this trigger cable is supplied when buying a Slave, how long will this trigger cable be?
