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?

Amp is in stand by when not in use 24/7  Preamp and disc player on 24/7 unless i go away for a couple days then they are unplugged from power

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 ?
