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?

Solid state should be left on all the time. If you have not tried it do so tonight and see if tomorrow it does not sound more liquid and effortless.
Currently i leave my electronics on 24/7/365.
When i did turn it off, with both the prior equipment, and my current stuff, it would take at least several hours for it to sound better.
Then if it was left on a full day, it sounded even better than if just for a few hours.
So, even though it costs money for electricity, I leave it all on all day long... As the sound is worth the added costs.
