The original post is pretty old but since your question is more recent, I’ll put in my 2 cents . I am presuming you are referring to the use of a 12V trigger between your MX132 and your MC602 you mentioned in a previous post. I have always used this option between my amps and preamps if it is available and have never had any issue. This might sound naive but I wouldn’t expect the manufacturers to provide this arrangement if there was a reasonable chance of damaging your equipment using it.
Despite various muting circuits that might be implemented to eliminate noise during start up or shut down, I do agree it’s a good practice to turn the volume down to zero before powering off.
