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?

I leave my Ayre K5xemp pre amp on all the time.  I don't think it has a on/off switch (or at least I have no idea where it is??).

I leave my Ayre P5xe phono pre amp on all the time, per Ayre recommendation.  

Everything else gets turned on and off with use.
I leave my system powered up 24/7 including a tube line stage and a tube rectified outboard SACD player power supply and tubed analog board in the SACD player.  I leave mine on for the same reasons as @soix mentioned above.
I leave my equipment on 24 / 7, it is ss. I have many amplifiers, but none have a stand by circuit. My understanding of a stand by circuit is very vague. Does stand by and being left on give the same warm up benefits ?
My last 3 systems, I left on all the time.  My 2 newest systems, I shut them off.  My 2 newest systems are McIntosh which has connections to turn on all their equipment by daisy chaining them together.  I flip one switch on the preamp, and the amp and tuner both fire up.  I leave it on for 15 minutes or so before I sit down to listen.  Since I am not leaving  everything on any longer, my electric bill dropped almost 25.00 a month and that is even after the rates have gone up.
