Simply stated, "YES"! And, when it happens I take full advantage and play till I can't play no more. BTW, this happens to me when I play my guitar. Sometimes it sound better or I enjoy my playing more. It isn't so much the quality of my playing but rather where my head is at. I bet if you were consistantly hooked up to a MRI or CAT scan it would show diferances related to your perceptual enjoyment of the activity even when the enntertanment is repeated. I bet it comes down to some sort of organic variable with in our bodies. Sometimes it is the chicken and sometimes it is the egg. I bet the same could be said for the enjoyment of food. Why does that icecream in the icebox taste so good one day and average the next? Again, I think that at times the real magic happens when the organic variables are in just the right balance. Or maybe it just the AC.
Do the Audio gods shine upon you?
Has anyone else had this experience or am I just nuts? You sit down for a quiet evening of Hi Fi listening and after some warmup time you suddenly realize that your system sounds dramatically better than it did the night before. I am talking about those little things like more resolution, low level detail. You know, those things that turn audiophiles on. I am almost afraid to turn my system on again for fear that the "audio gods" have abandoned me.
