Does your system hate you when you ignore her?

I've not been able to listen to my system seriously for about 3 weeks. I just sat down to Emmylou Harris' " Red Dirt Girl" on HDCD. My first impression was that the soundstage was not as wide as I expected. I suppose that it's possible that components need to re-burn in after prolonged periods without being energized. I also suppose it's possible that one's trained listening skills may need refreshing after a period of atrophy.

Have you experienced similar things? What were the variables that you were able to eliminate, such as experiencing the same effect on two different systems, one rested and one not, in the same time period after not listening.
