Breaking Gnus! 

More bad Gnus. 15 million people at risk. Slow moving heavy rain storm, today through Friday, Texas to Arkansas. 25 tornados (count em!) and flooding hits the South. Ten states involved.

Hi,
a well broken in equipment will come alive faster after turning on. I never leave them on when away or not having a long listening session. Most high end units have a soft start so no big harm there. In absolute terms leaving a unit 24/7 on will not bring a longer life as you will need a more frequent change of caps, tube replacement, change of equipment and a heavier electricity bill.
