Hopefully the amp manufacturers produce their products to be reasonably stable at a "range" of temperatures. The few degree swings in a normal day should not amount to much once the electronics heat up, and then settle in.
Going from a very cold room (heat turned off) to amp turn on might produce the biggest swing in thermal shock on connections, solder, caps etc. In the grand scheme of things it really should not mean too much.
The biggest effects will be on those devices that change mechanical energy into electrical energy and vice-versa, things like speakers, mics, cartridges, where very precise tolerances are required.
We did a study on microphones many years ago and found several actually sounded better "cold". It is just going to depend on all the ins and outs of your system....
Uniform temps should be better, but most homes should be 68-72 degrees. That range shouldn't mean too much.
