Variations in how your system sounds?

Apologies if this has been covered elsewhere.
My system sounds consistently good to my ears for the majority of listening sessions but every now and again (say 1 in 20) it sounds slightly 'off' -- not its usual self. It is a very small difference but i do hear it. I would describe it as a slight lack of focus and dynamics. This has happened through many changes of all components.
Is it my mood, or hearing variation? Do i need to filter my power? Do you have similar experiences?

I used to have this problem. After much frustration & tweaking,
I think that power regeneration & fairly regular demagnetising (demag via power supply) solved this.

You might consider that your hearing changes day to day, and throughout the day. It is likely not your equipment at all, but you. Humidity levels, exposure to other noise, barometric pressure all affect your hearing.

Dirty power could also be the culprit, although you would likely hear differences more frequently, or at different times of the day if that were the case.

Great post Meiwan, I agree 100%.

I always attributed it to psychology, or physiology (ie my hearing). Also, have you ever noticed how if you leave on vacation for a while, how sweet your system sounds on return?

this has come up before with no final resolution agreed upon.

fwiw I have experienced the same thing and can not pin point it to anything specific wheather it be humidity, my mood, power quality, time of day (except after 11 PM).

The only obvious difference for me is after about 11 PM the sound is better and I am sure that is because my neighbors are using less power but that is not what this post is about.
