I have noticed that moving furniture around, plants, TV positioning etc. changes the sound, so stands to reason that the same would happen when moving two honking monoblocks around.

I'm nigel.
Make sure you keep your tube gear a good few feet apart from your wireless modem.
I moved some gear into a new rack a couple of months back and without thinking positioned it close to my hub.
The modem induced a awful low pitched thrum into my tube pre, took me quite a while to trace my error.
