Romy,

  Why do you think the improved sonics were related to the residual noise or more precisely the hypothetical delta of noise components from one day to the next? You were very non specific about what was better and to what degree. If you are perceiving better sonics because of less noise from the equipment when not playing musics or greater perceived "blackness" between notes that might have some relationship. I would also suspect noise if I heard better treble without hearing as much relative improvement in the bass. However, other kinds of changes to sonics like dynamic headroom probably have little to do with minor changes in low level whistling noise levels. Even if the power is pure from the pure power device there are all kinds of radiated garbage in the air that can enter cables and components directly.  I should note that I have heard some days and (more) nights of unusually good sonics in the past year on my system too. I live in a Virginia suburban location  not resembling your location. Aren't we at a sunspot minimum period? I don't have a clue if that could affect things but at least it works on a large scale. Other possibilities are upgrades to the electrical grid although if they introduce all of the proposed regualtory devices and metering devices with their digital hash the left hand could take away what the right hand gives
