How often is your system "good"?


In a recent article in Stereophile, the author wrote, "When my system is good, it forces me to appreciate artists and songs I'd never noticed before."

My presumption is that the author meant that his system sounds better some days than it does others.   I think this is an accepted fact.  I believe my system does better early in the morning and late at night due to power constraints.  I have a voltage meter on one of my outlets and I feel better about the sound when the voltage isn't sagging.  

My question for readers here is how often is your system good?   And to what do you attribute the goodness of your system from one day to the next?

No doubt the quality of the power we receive from the local utility company varies.  I do not find that the quality of my sound varies anymore.  For me, the magic bullet is the power regenerator that all of my components receive juice from save my power amplifier which receives filtered power.  I know the regenerator/conditioner issue is a controversial one.  I only relate my experience including right now as my sound is great.  Prior to the regenerator, I experienced what many other audiophiles relate...that their sound is best late at night.  The implication being that fewer devices are in use on the utility line and hence there is less distortion feeding the system.

As long as things stay as they are here, I won't change a thing.  If performance changes at some point, then I'll need to adapt and work to find a solution.  Life is too short for compromised sound due to the quality of the electricity we feed our systems.
