Gents, I think Garfish has nailed it. I think this is a real phenomina and it has everything to do with our frame of mind or mood when listening and nothing to do with our ears or systems. A good analogy would be the "clean car seems to run better" syndrome. Gentlemen, perseption IS reality!
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.
