Seems like the best "upgrade" for tube amps....

...is to leave the amps on for a few hours before playing. I've noticed recently that when I turn on my Joule amps and let them run for hours, it makes a huge difference in the dynamics and high end sweetness. It gets hot in our house, but it's worth it. Is there a technical reason for this?

If I don't worm-up before lifting weights or swimming, I'll get sore or can get injury.

QuickSilver, VTL or Manley poweramps operate in 5...10min according to the measurements I've done in the past with analysing bias and transient responses via oscilloscope.
If I play same record first in 10m and then play it again in half-our, it might seem to sound different and so is CD. If I turn off the poweramp no matter tube or SS and turn back-on and after the settle time play the same, it will sound different again(actually that's the case of the most of improvement I've experienced).
