Noise when shutting off power amp? Help?

I have a Classe 100 power amp, and preamp, and when I shutdown the power to my system Power amp>preamp> source(in that order, which I believe is correct), I shut off the power amp first, and when it clicks off it sends a noise through to my speakers. Is this normal? I had a Rotel amp before this and it never made a sound. Should I just turn the volumn down on the preamp before I shut the power amp off?

I don't mind the sound the power amp makes shutting down, but it concerns me that I hear it through my speakers. I find this quite odd.

I would conclude amps differ in their behavior when powering off. Case in point: I have had 2 amps from Belles, the first was the HotRod 150. It never cared about sequence when powering off.---The 150a ref. I now have requires the pre off first---or change to an unused input,by remote,in my case.---If it ain't music,I don't want my amp reproducing it.
