Have you ever hated the sound of your system one day, and loved it the next?


Last night I went to bed thinking my system was going down the tubes. This morning I loved it.
 Last night it sounded painfully bright and unbalanced.  This morning, on the same CDs, it sounded full and rich.
Now, I ask you, is it the system or me???
  I understand changes in electrical currents from the wall can play a part, but I have an expensive power conditioner.
 I was just wondering if this is a typical bugaboo among audiophiles.

Absolutely not!  My system just doesn't sound terrible on some days.  On some days I get less involved when listening to music, but on some days food doesn't satisfy as well as on others.  I agree with what Prof said above, it's you.  Stress, sleep patterns, diet, sex life, noise exposure, bowel movements, drugs (both legal and others) and biological rhythms can all have a serious effect upon your ability to enjoy the sound of music.
Whoa! Hey! I never thought I’d live to see bowel movements and sex life in the same sentence. What the ding dong?!
I’ve identified the problem. It’s a tube in the preamp that was going bad.
it was intermittently causing distortion and reeking havoc with the sound, from one day to another.  After replacing the tube, the set sounds better than ever (or so it seems after the nightmare.)
