Does not matter where they were repaired the only thing that matters is the humidity in your listening room.

  Just out of my own curiosity, is there an optimal humidity for stats? In my own listening room I've measured humidity ranging from low 50's to low 20's. In spring and fall when windows are open the humidity ranges from mid 40's to low 50's. During air-conditioning season it usually in the mid 30's. In winter it ranges from low 20's to high 20's.

    No stat really likes humidity but some of them tolerate it better than others.
    
    In general keep the humidity between 30-50%. This is the range that is the most comfortable for people and it turns out stats will like it too!

ESL 63s take a while to get powered up completely. If the speakers have not been plugged in and turned on for a while, this could be causing some hiss.

Since you don't describe the "sound" its pretty hard to guess. It also could be you are hearing something emanating in the front end of your system or in your amp.

Is the rest of the system off when you hear the "sound" ?

Remember: DO NOT play a signal through the 63s unless they are switched on.

  If the speakers are working correctly they should charge instantly as a practical matter. There may be some very minor rustling when first energized but this should disappear in a few seconds. I highly recommend that the speakers be turned off when not in use given they charge in a few seconds. There is no benefit to leaving them on all the time.
  
  The speakers will not be harmed if signal is applied and they are turned off. I have done this hundreds of times. About the only way you are going to damage the speakers if they are turned off and applying signal is if you have a large monster amp like I do, 200-300 watts, and you keep turning up the volume control!

    From the factory Owner's manual:
    
    "When the AC input is switched off or disconnected the signal input protection circuits operate to preven excessive signal being fed to the loudspeaker elements and care should be taken to ensure that the loudspeakers are not driven for long periods (minutes) with no AC applied."
    
    I have always taken this to mean "do not do this at all."
    
    Obviously, Kent's long experience with the speaker trumps my interpretation.
    
    I guess one of the reasons I leave mine powered up pretty much all the time is to keep from doing the above, so I have been wasting a bit of electricity.

      The factory is being conservative as they should be.
      
      Any stat should be unaffected by playing signal with no power. Nothing changes from the audio side of the equation with or without AC power applied. The only thing AC power does is energized the bias supply to apply voltage to the diaphragm.
      
      With the Quad no power does defeat the protection circuits but these are only required under extreme drive conditions. There will be no problem unless the user decides to dump 200 watts of power into the speakers. Most amps people use with Quads, even if clipping, will do no damage.
      
      Leaving any stat energized all the time just exposes everything to high voltage all the time. High voltage degrades everything over time. There are some exceptions the original Quad should be left on all the time. But this is a completely different beast versus the 63 and the original Quad design approach is quite unique among stats.
      
      I understand the caution. The typical user is not aware of these things and erring on the side of caution is always a good idea. But turning them off when not in use does no harm it is actually good for them. And applying signal to the speakers when powered down does no harm within reason.

        Thanks, Kent.
        
        Naturally as soon as I realized I did not need to leave the speakers on all the time, the obvious question was...hmmm what's the electrical effect of leaving them on all the time?
        
        I am turning mine off at the end of the session from now on.
        
        Thanks again...sho is nice to have somebody who actually knows stuff around.

        What about the Stax F81's and F83's? These seem to take a long time to energize properly, so I do leave mine plugged in all the time. Is this a mistake?

        The Stax F-81/83 like the original Quad should be left energized all they time. The conductive coating used in both speakers require that they be left on. This will present no long-term problems.
