Warming-Up Amps w/o Inputs or Speakers Attached

How dangerous is it to warm-up amps without inputs and speakers connected? When running A/B comparisions between gear it's difficult to truly gauge differences when one piece is good and hot and the other stone cold. What about the differences between doing this with SS vs tube amps? Can you just plug them in and let them cook?

"The output devices MUST have a load to dump current into, or most will overload/fry."

I don't see why. SS amp is basically voltage source that will run with or without load.

Herman,

Even when driving input 20W should be enough since average music power delivered to speakers is only a few percent of peak power.
