    Default heres a potentially stupid question

    so i picked up some new toys recently (its an illness), and since they both have transformers in the path, Ive wondered if there is a certain amount of time to let them "warm up". Ive read the manual (for the one, the other didn't have one) and nothing was mentioned on this.

    Ive read somewhere (think it was here, can't remember) that some people prefer to leave their equipment on all the time. Other than the hydro bill going through the roof, is their any validity to this? I mean, are you really going to notice a difference if you leave your stuff on for a while before you use it?

    if theres anyone that does, your thoughts would be much appreciated. thanks guys!

    Valves, yes. My Brauner didn't start to wake up until half an hour had passed. Transformers? Never heard of. As for "up and running" - I've had my studio up and running for years. I think 17 months with just a few restarts for the computer is the personal "record". Nowadays with a smaller setup - I kill the rack in the night because of the shiny lights and a 28 square meter flat (apartement for you strangers). The computer is always on, though.

    Transformers do not need to warm up unless they have been cooled to near absolute zero, in which case the superconducting effect would play havoc with the impedance, not to mention your liquid helium bill.

    It would be the audio equivalent to dividing by zero.

    Yep - it'll try to sound like infinity. But just for a while.

    Paradoxically, infinity is really quiet!

    How many dBs can an infinity of quietness reach?

    Unless you are using a nuclear powered NibNob, or one of the older, steam powered ones, I don't see how it makes a major impact on your water bill.

    In the old days when electric power was cheap and many, if not most things ran on tubes people left stuff on all the time because

    (A) It was believed that turning tubes on and off all the time shortened their life due to thermal cycling (probably true) and

    (B) Tubes take time to warm up and stabilize sonically (definitely true).

    The habit carried on, even after most stuff had become solid state, the reasoning being that thermal cycling still affected solder joints (maybe, over a very long term) and the life of semiconductors (probably true in the early days when production methods were somewhat dodgy, not at all true of modern devices) and some people still insisted that gear needed warming up.

    Of course if you left a room full of tube gear on all the time now you'd need a second mortgage to pay the electric bill.

    You'd make some of it back in reduced heating costs though. (Speaking as a Brit... We had snow last Saturday in Birmingham.)

    its funny, of the gear I own the thing that changes the most as it warms up is an FMR Really Nice Preamp. Takes 15 mins before it sounds right.

    at least you don't live in newfoundland. 50 cm of snow and 100km winds.

    so all i gotta do to lower the noise floor is supercool my equipment? how cold for infinite headroom

    Unless you are using a nuclear powered NibNob, or one of the older, steam powered ones, I don't see how it makes a major impact on your water bill.
    for some reason, electricity service is referred to as hydro over here, probably short for hydro-electric. hehehe, nibnob. been a while since i heard that.

    The habit carried on, even after most stuff had become solid state, the reasoning being that thermal cycling still affected solder joints (maybe, over a very long term) and the life of semiconductors (probably true in the early days when production methods were somewhat dodgy, not at all true of modern devices) and some people still insisted that gear needed warming up.
    aah, yeah was never sure if it was a sound thing or a maintenance issue. thanks for that, john!

    like i said, probably stupid question. but i learned something...you gotta keep your equipment the same temperature as your beer.

    They used to tell you to leave computers on because supposedly the speed and precision of the hard drive blah blah whatever.

    I don't know if that was ever true, but a relative of mine in IT told me, nah, he turns his off at night; it's just a waste of electricity. So I usually turn everything off before I go to bed or if I'm going to be gone for a while.

    Obviously if you have outboard gear with a built in diesel engine like the NibNob 2000D, you leave it running. That was also true for the earlier coal-fired ones. Once the boiler gets cold it takes quite a while to build up the steam pressure again.

    It was said that the startup and the shutdown of a computer was what deteriorated the parts the most. I'd guess it's mainly a HDD related thing. I'm on SSD now and the startup time is under 10 seconds - but I still like to have my computer accessible at all times. Call me vain. I just don't like the startup chime.

    Is negative infinity really loud?

    What the fuck does a computer have to do with audio????
