California electrical shortage audio

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?

Massvm: I then have been using the term "Brown out" incorrectly to describe the situation where the power drops for only a small portion of a second. This is what I am experiencing at this time (if the APC unit is accurate in testing for this). It appears that we are just having fluctuations in my area (approx. one every 30 seconds or so) instead of a constant reduction of either voltage or amps. I really don't know the difference between the two other than that "amps" can make or break you (I have been shocked by both low and high amperage lines with the same stated voltage and the difference was quite apparent). An electrician told us a couple of years ago that we had problems with low amperage in our building which was why the light bulbs were only lasting a couple of weeks (we also went through a computer fan every 6 to 9 months or so during this period as the motors burned out). Since then the electric company replaced the power transformer that feeds our building and now things seem to be back to normal (as far as light bulbs, anyway). I am a bit concerned about this issue as I have a lot of money (for me anyway) invested in my current system, that I am actually satisfied with and wish to keep long term.
