California electrical shortage audio


California is experiencing an electrical power shortage and has random brown outs. Many current audio products are now designed to be left with the power on (they say producing no harm or wear to the unit). Many manufactures recommend that leaving the power on allows the circuitry to remain at a constant operating temperature, providing better performance and longer life. Should I continue to leave my CD Player and integrated amplifier on in mute mode considering the California electrical power shortage and random brown outs? thanks...

Hi gentelmen, i live on the island of GUAM. We get power knocked off frequently,along with electical storms. I have my cd plugged into a audioprism foundation 3 and my pass x350 direct.I have not had any problems.I leave everything on or running music thru it 24hrs. a day.
MY pass does sound better i noticed after being on 24hrs.a day and i mean on not in warm up mode. The sound is smoother and more revealing.
There are actually several issues involved here. For one, there is the danger of damage from turn on surges, which is the reason many manufacturers do not even provide an on/off switch for amplifiers or preamplifiers. However, if your electronics -- and especially your amplifier -- have a "soft-start" feature in which it takes anywhere from 15 seconds to a minute to reach full operating power (longer for tube amps, shorter for solid state), this is less of an issue. Secondly, my equipment does seem to sound better when left on all the time, which is what I usually do, but not without a little trepidation. Bryston (manufacturer of both my amp and preamp) has no formal recommendation on the subject. Third, even though all of my electronics are protected by professional/studio grade surge protectors, I always turn everything off during an electrical storm. This decision is based on experience. When we lived in New York, a power pole near our residence was struck by lightning and all of our light bulbs were blown out; and the permanent plug-in plastic night lights used by our then young children all melted. Several of our neighbors lost their well water pumps which were in the on cycle when the lightning struck. A dealer friend of mine lost several pieces of equipment when his store was struck by lightning, and he was using surge protectors. And finally, Sam Tellig in STEREOPHILE reported losing a Bryston integrated amplifier when a nearby power pole was hit by lightning. Fourth, and relating to the issue of brown-outs, when we lived in California, we were once subjected to a very localized brown-out (it encompassed a two-block area) due to a transformer problem and my amplifier suffered very severe damage to the power supply. Obviously, there is no perfect answer to fit every circumstance, so we must each make our own individual decisions. All in all, I personally would rather be a little safe than a lot sorry and thus take the actions outlined above.
I live in LA and have been able to monitor the frequency of the Brown outs with an APC power supply that I recently added to our computer. The APC has a "chirp" alarm that goes off when the power drops. Well, it chirps merrily all morning and throughout the day. It used to settle down after midnight, but this is no longer the case as I suspect that the power company is reducing their power output after that time. The Brown outs are not noticeable to me when I am playing music in that they do not cause MY DAC to lose data or cause anything to malfunction. I suspect that the power supplies on my gear have more than enough juice in reserve to cover these partial seconds of power reduction. I do not however play music at high volume. I now turn my SS amp off in between use to conserve energy (it idles in class A) and do not have standby on my tube amp. I do still leave my DAC and player on 24/7 because they both sound a bit lifeless (for many days) following being powered down for any amount of time. What is the difference between depleting the power supply reserves when playing complex music at high volume -vs- having the power input reduced for milliseconds at a time as far as damage to the equipment? I know that steady low (reduced) amperage is hard on power supplies (and light bulbs) but this is not a "steady" reduction of current (amps and voltage), not yet anyway. I also wonder what effect this would have on the power supply of a power supply/conditioner such as a PS model?
Dekay, you will not suffer a loss of current during brownouts. In fact just the opposite is true for most (non-resistive) components that are powered up during brownouts, a rise in current to account for the decrease in voltage while maintaining a desired (let's call it constant) power output. That is the crux of the biscuit.

Brownouts are one of the first phases of power reduction, and do not last short periods, but indeed rather long periods (hours) as the utilities lower the overall electrical distribution grid voltage to compensate for lack of production. The question you ask about the depleting of power supply (amplifiers and the like) reserves compared to brownouts presents two very different cases as I understand it. To maintain the stored energy capacity of the inductors and capacitors of the power supply requires a given AC supply power. If voltage goes down, current goes up to maintain that same power output. Large inductive loads -- AC units, refrigerators, inductive furnaces, etc. are all subject to the same issue. But I think that you may be able to live without your inductive furnace during the brownout anyway.
I realized I didn't address the "brownout" part very well. Brownout gets it's name from the fact that light bulbs, which are resistive loads, glow less brightly during this phase of utility energy conservation. Since the bult is a resistor, as voltage goes down, so does current flow. Not quite the same issue as motors that are being called upon to deliver 1.5 h.p. They simply draw more current at the reduced voltage to obtain the same power output.
