I agree with Jax2. Tubes dont take long to warm up and sound good after an hour or so. There is no need to leave tube stuff on when not in use.
Solidstate gear is a little different and in my experience sounds better after quite a long period of being left on. The latest gear after being burnt in doesnt suffer as much as some of the older stuff though.
Save energy where you can. As the flood water washes your house away followed by the desert sands covering the plot where it stood, try explaining you used to leave your hifi on 24/7 because you got sweeter highs and slightly more separation!
