I don't leave my equipment powered "on" all the time, don't want to consume that much electricity. My amp and preamp "automagically" power themselves off after so many minutes of inactivity (no way to adjust that), and my DACs throw off a lot of heat, even when in "standby" mode.
I do find that the first 10 minutes or so, my system doesn't sound the best, but after that short amount of time, seems to find its stride.
