good listening/bad listening

i think you are talking about the difference for enjoyment and critical listening. i think we all go through that. most of the time i listen for enjoyment but every once and a while i will go through a critical listening phase.

It mostly has to do with the way you feel. If you are into subjective audio, you should accept your own subjectvity and stop blaming the grid!

I do also. However, in my case, I believe it has to do with my mood at any given time. By mood, I actually mean the number of cocktails consumed.

I do, too.

However, I do most of my listening at night when the power quality should be better than the day & I still "say, ehh why does it sound like that...I don't remember it soundin like that?"

I think it has to do with stress or how I'm feeling physically as I've noticed that when the same tracks are played later the same night, they sound better.

With that said, "varying power quality" is a factor, also. Another factor may be equipment warm-up time.

Other factors, less well understood, may also be involved.

To mr Bad Listening is when you are drinking with friends, boy that can get expensive if you are not cautious!
I have those good days and bad days, we just had a get-together with members in our little "Ears and Beers" club and wow the system made me proud!
