Has anybody Cryo'd their complete amp-results?

I was thinking of doing the same thing to my entire tonearm
and phono cartridge,but I'm backing away from the idea.
In your case I was told never to have electrolytics cryo'd.
I'm not sure if you have any of these in your amp.But I would deffinately get something in writing from them for guarantee if anything goes wrong.I will get my cables cryo'd
soon as a safe way too go.
