Does anyone leave their amp and preamp on all the time?

I listen most nights after work. I find that the system takes a while to warm up and sounds it's best if it has been shut off. So I leave it on. I always have and this is vintage stuff. The amp is a 25/25 Bedini class A. It stays warm but never hot. It has never caused an issue but recently I've been speaking with others that were stunned that I would do this. So let me know if I'm the only one that lets it run. Do you shut off the equipment after each session?

Putting the energy consumption issue to the side here is something to consider in terms of component reliability. I have had two sources tell me that electronic component lifetime is related to the number of power cycles (on/off). This came from discussions with a supercomputer designer as well as discussion with a speaker manufacturer on the topic of crossover design. I would guess that slow start circuits could also reduce the impact of on/off power cycles to a degree. Of course leaving a component powered up all the time does not make sense for a tube amp with the power tube life issues and heat.
  Personally I leave my TRL Dude preamp and Samson monoblocks on all the time unless I leave on vacation.
