I have a stereo test CD, and it has a few tips at the back of the booklet on getting the best sound out of your stereo sytem. One of them reads as follows: " If you have solid state equipment, consider leaving it on all the time. It won't use up much electricity at idle, or be dangerous, and it won't 'wear out' from being on. In fact more stress is put on the equipment when it's turned on. Why should you do this? Because many audiophiles and engineers claim it takes at least 24 hours for the electronics to 'warm up' and sound best. Try this: Turn your system on and play a favorite piece of music ~ one you know well. Leave your system on for 24 hours and play the piece again. If you hear no difference, don't bother leaving it on. But if the music sounds warmer, fuller, less harsh and more natural, don't shut it off!" O.K. They're talking about stereo amplifiers here, but, how does this idea sound to you? Also, are stereo amps and musical instrument amps that different? Your comments/thoughts please. Mike J.
