Barometric pressure, temperature, moon phase?


I’m off work tomorrow, made sausage and peppers for dinner, and now I’m enjoying a Sazerac on a beautiful summer evening, listening to Joni Mitchell.  All is right with the world, at least at my house.  But...  the stereo sounds ever so slightly, not quite there.  It did the other day, but tonight, it’s missing some tiny bit of something.  Has this ever been experienced by any of you out there?  One day magnificent, another day, just ever so slightly not quite as good.  Atmospheric conditions?  Mood? Magnets?  Thoughts?

You may find http://ielogical.com/Audio/WinterBlues.php interesting and specifically http://ielogical.com/Audio/WinterBlues.php#TheFly for the effect of temperature on speaker XOver

You did not mention the source. LP playback systems are subject to all manner of temperature related foibles: bearing tolerance, lubrication viscosity, cantilever suspension compliance, vinyl plasticity.

Do you note levels at which you play a particular piece?
How repeatable is your level control?

When mixing, we calibrated the playback level to the speakers to ±0.1db. The room was temperature controlled to ±1.0°F. When we were satisfied, we always checked the next day on cold monitors. Mixes made in the heat of summer sounded different even though the room temperature was nearly identical as rooms were not humidity controlled. Line voltage and dirt varies considerably in Los Angeles, so we recorded and mixed late a night when the vagaries were minimized.
