How long daes it take your gear to warm up?

Assuming that one turns off/on the audio equipment every day. How long does it take for your gear to perform as it best after a cold start? I ask because my Rotels RA-1090 need about 2 hr to really shine, otherwise the highs are ear piercing and the bass notes lack some punch. Any of you have to go through a similar time of warm up period?

A couple hours for my all-tube system, though it's at least listenable after 45 minutes.

My stuff generally sounds good from teh start but warm up does not hurt. Its important to me to be able to sit down and enjoy without a wait. Even the ARC sp16 tube pre-amp, which has a relay that turns on once the device warms up after power on in a matter of seconds, is 100% listenable out of the gate. Also I leave my SS DAC and power efficient Class D power amps on most of the time. You can't do that generally with most tube gear without reducing tube life.

Maybe its just me and my tin ears, but I think my tube pre/amp sounds pretty stable after about 1/2 hour. No option of leaving it on 24/7 like I used to with my SS gear.

Oh yeah! Go through that stuff we do. I find my system sounds its best after being on for at least 3 to 4 hours, and really liquid and flowing when it's been on for about 8 hours and the amps are as hot as the core of the sun.
I have solid state B.A.T. monoblocks (VK600se's), and I had big Krell's before that. Both of them you could fry eggs on after about 4 hours, which is when they are/were in their groove and all is right with the world!
