System Warm Up

Many people think that 2 channel audio electronics sound better warmed up. Could be my imagination, but I have always thought this also. I've considered just leaving my system on all the time. I'm curious if any of you guys leave your systems on all the time. Obviously it's not a very green thing to do, but....

    When I ran all SS gear? Absolutely. With all tubed gear? No.

    I leave my amp on 24/7. Seems to be easier on the amp from what i've read, and that way i don't have to endure the 30 minutes to an hour of it sounding like dog ****.

    My experience is different w/ my Audio Electronics (Cary) tube power amp. After 1/2 hour is sound pretty good, but after 1-3 hours it is all together a better and more refined sound. The tube preamp I owned in the past w/ kept on 24/7, by recommendation from the manufacturer, so I don't have any comparison other than the manufacturers recommendation.

    There's two sides to this..

    Do what you want after this little research. Cost is about the only issue and electronics don't use very much.Turn on does shock the components so if your always turning on and off, that might harm them down the road.

    Here was some good advice not long ago. If it really warms to the touch in standby, turn it off. Your just cooking the component for no reason.Just give it a 1/2 hr. warm up for optimum performance after turning on.
    Most people just listen to music and watch movies. I EXPERIENCE them.

    Pre and amp are left on 24/7 as recommended by the manufacturer. DAC is on 24/7 as it does not have a power switch. Active crossover is on as its between the pre and amp.

    Solid state components are on all the time. If you turn them off for some reason, then I use as a rule of thumb 45 minutes of warm up time to get the internals to stabilize. I've had (still have one) two pieces of high end gear that came with no power switch because the manufacturer recommends leaving them on 24 X 7. For solid state gear this will electronicall extend the life of the internals. Like Tony said above, power up shocks the components.

    SS yes, Tube no.

    Agreed, the manufacturer of my CD player puts a master power switch on the back panel and says to keep it on which keeps it warm all the time, then it has a standby switch on the front panel. Plus I think all my stuff sounds better when they get warmed up, so they stay on.

    All the amplifiers I have owned have had a master switch which I left on all the time my current two channel amp had a standby swith only it stays on unless you unplug it.

    Every time you are ready for a tune session just think about foreplay for a few minutes or so.

    My Simaudio power amp has BOTH the master power and standby switches on the back! That’s fine when the unit sits on a table while it’s being developed but a real PITA to reach when placed in a rack. I borrowed some Tinker Toy pieces to create a wand to reach the standby switch. Need to remember to make something more permanent before they notice.

    I generally leave my DAC, preamp, and amps on 100% of the time Friday through Sunday, when they’re being used the most.

    I turn the preamp volume down and disengage the speaker output switches when the stuff is on but not in use – really to avoid any potential mishaps.

    Durring the work week, I’ll turn them on/off as needed.

    I do think the amps sound better after they warm up a bit – seems like the sound is one dimensional and uninvolving prior to warm up.

    Amps stay on in standby all the time, I'm too impatient to wait for them to warm-up.

    Both of my class A SS amps I turn off when I'm not using them as they create a ton of heat and use too much electricity.

    My preamp stays in standby mode, but my amp runs too hot to leave on 24/7. The system generally comes into its own after about 40 minutes.

    When I had SS it was powered on almost all the time and if turned off would require at least 45 minutes plus to start sounding its best. I now have tubes in all my components and I have them off when I am not going to be listening for more than two hours. The tubes do have a set life and some are getting expensive to replace. (Never should have tried those damn NOS tubes:eek:). I do find my system sounds good after one hour on but better after two.

    I turn my stuff off after use. It takes a good hour or so for them to warm up. My tube gear have very crappy bass for the first 15 mins.

    I just turn them on as soon as I get home from work, take some ganja, and by the time I'm ready to listen, everything's warmed up:).

    I was wondering about this, too...I always shut my NAD completely off because I figured standby would shorten the life of components since there is always current running through the amp. I always found it odd that the NAD remote could not turn the unit off, only standby, and the power button on the actual unit only puts the unit in standby when you press it; you need to push a source button to fully turn it on. Maybe this is because they expect you to leave it in standby?

    I prefer all my gear warmed up, SS or tube and myself lubed up.

    I think he means the surge, no matter how controlled, when powered up.

    Large current inrush when powered up.

    Tubes are like light bulbs, the shock of heating up and cooling off cause the most wear and tear. So tube equipment can be left on if you want to extend tube life.
    I can think of no reason to leave solid state gear on constantly.

    Manufacturers of solid state equipment do. That's why they have either standby mode to keep the current flowing or no power switch at all so as to keep the current flowing. Surges of current does reduce the life of solid state components. Going by your apparent train of thought a solid state component should never burn or wear out.

    I guess I'll be keeping my NAD on standby from now on. Hopefully it doesn't use much power.
