powering up pre-amp

I read in another thread about not having amp powered up till the pre-amp is on, and powering off amp before pre-amp is powered down. I usually leave my amps on all the time and if I am running the pre into my bypass inputs on my Rotel, as long as I am not on that function could I power down the pre-amp and power it up without the worry of the SS amp being on? I know I will have top remember to have the Rotel either off or on a seperate input function, but as long as I follow these step, the amps being on should make no diffrence correct?
Pre amp is coming tomorrow so help today would be great...thanks as always
