I absolutely agree. Once the components and cables become constant in your setup, other variables such as quality of power, outside noises and personal state of mind greatly affect the musical experience. However, when all are in concert it is an amazing and enjoyable experiience.
My system always sounds best in early morning and late evening. Yes, many people would write that off to the quality of power running through my house at the time, but in the mornings I wake up fresh and eager and in the evenings after a hard day at the office I'm ready to unwind and relax. So I think in both cases my mental state is in one of relaxation and acceptance of the upcoming listening experience. During the middle of the day I'm probably less relaxed and have too much on my mind.
