How long daes it take your gear to warm up?

Most SS Class A power amps can draw 600 to 700 watts each. To leave them on all the time, lots of heat and utility cost. Some of us most own a power company. All my gear is left on less my power amps. One to two hours for casual listening , four to six hours for critical listing. Lots of Red wine is also required.

Usually 20 to 30 mins to all my SS gear..as the manufacturer recommends.

My CD player is left on 24/7/52 as for the rest I turn on the phono preamp, turntable motor and preamp two or three hours before listening then go for the amps. If I leave town for a day or so I unplug everything. Turning on the preamps and motor seems to let the system come together more quickly and yes it does mean buying new tubes about once a year. Sigh! My amps are class A and they get put on when I am ready to listen and it only gets better from there.

I never understood the logic to leave equipment on all the time. However I do appreciate the posters that state that their sound is wonderful if equipment is left on. Life is short enough and if this helps make life better and your music is great and this is painless for you, then by all means, leave it on. Except for tube equipment which does have a specific life. equipment that does not have heat issues (class A amps, etc.) really won't have a drastic effect on components. Don't misunderstand me, there will be a long term effect by leaving it on. equipment life will be shortened. But, if it sounds good and it is worth it to you, the by-all-means. It takes my system about 20-30 minutes to have great sound. However, I really haven't noticed bad sound with 10 minutes warm-up. it still sounds great. I typically turn my system on when I know I'm going to do quality listening, go do something else,like cook, open a good bottle of wine and let it breath, get a good book. by then, it is good to listen. experiment. Turn the system on and listen immediately to your favorite music. Take notes. Is it flat, no dimension? how's the sound stage (assuming there was one in the first place), etc. Then next day, turn it on and listen after an hour, to the same music. take notes again. Then, leave it on all night and day and then go back the next day and listen again and take notes. Compare and see if there were major differences. That is a true test. Also, if you can get others to help with the listening test, that would be better.

But, unless you want to replace tubes more often, I would not leave tube equipment on.

Minor1, you say that leaving equipment on all the time will shorten equipment life. Do you have proof of this or is this just your theory?

I ask because I know some capacitor manufacturers who recommend cycling (turning equipment on/off) to help speed up break in and extend the life of their product. On the other hand, many other electrical components like switches, relay's, resistors, etc are more prone to failure due to the in rush currents that come from cycling. So it would seem to me that leaving equipment on 24/7 may shorten or may extend the life expectancy of your audio gear. I have no charts or graphs to back up my theory, just my $0.02.
