What is turn on/off sequence of amp and pre-amp?

Same question as Phil, I've been using Standby before shutting down and then obviously it's in Standby mode when I power on. Is this necessary? Or maybe even detrimental somehow?
Although my amp doesn't make a pop sound. It does make a thunk noise when going from Standby to Active.

mr_m do you use the Standby switch at all during the power up/down process?
