K4700. Why not mount R23-R26 on a symmetrical power supply?

Why should I not mount the resistors R23-R26 when having an amplifier with a symmetrical power supply?

Is it really a good idea to power off/on an amplifier without any load at all?

I will be using K4700 on a QUAD 405.

Because when there is an error in the amplifier, this amplifier is loaded asymmetrically.
I told you this already by mail !
It’s a speaker protection, it always better to protect the speakers, they are mostly more expensive !
