good listening/bad listening

Do you ever listen to your system and say WOW that is great? It really sounds excellent.

Yes, every time I switch it on. Weird I know but it is still amazes me even after many years.

Then, other days you say, ehh why does it sound like that...I don't remember it soundin like that?

No - my system is constant - it does not change in response. The only time I don't enjoy listening is when I have a cold and my ears/sinuses are blocked. If your system does not enthrall you every time then you there is something not quite right. Music played well at realistic levels is always extremely impressive.

There is no "bad listening" from my system. I always think to myself: wow, that's fantastic sound, that's real high end. Well, I don't bother "thinking" that all the time: it's just there as a matter of course.
For listening during conversations or vacuuming or other chores I have a second little system in the same room which is astonishingly good. But for serious listening the high end system only..... and no regrets!!

Stress, sinuses, tinnitus -- the state of any of these affects what I hear and how I hear it. Dave

PS And there's always earwax build-up.

There are definitely physiological aspects that affect our listening. The most obvious is when we have a cold (as Shadome pointed out) and our ears are stopped up. Imagine now, what if your ears were stopped up, but you didn't really have a cold and didn't recognize it? Your system would sound muffled just as if you had a cold.

I know there are things that I do that have a dramatic effect on my listening. If I haven't had enough sleep things don't sound very good. If I haven't excercised (I have no idea why this has an effect, but it's pretty profound for me, particularly at the high frequency). After flying my hearing is not as good (and I wear ear plugs to reduce this effect).
