Is thing always happen to you?
You are listening to your AV setup and you feel like you have the best sound of all HT AV setup in the planet. You think you finally found the right settings for your setup after years of tweaking and turning. And you want to leave that settings for the rest of your life.
Then a day or 2 or 3 days later you listen to your setup and feel like is not as detailed, warm or lack of treble or bass or too boomy, whatever. You check all the settings and all are the same nothing moved not even a smallest furniture. You play the very same inputs (cd, dvd, sacd, tv) and still can get the same best sound that you have few days ago. And your hands are getting itchy again to do more tweaking and turning.
Why is this hapenning? Is it because the room ambient temp, weather or climate are different few days ago?
Is it maybe my testestorone or blood pressure or cholesterol or blood sugar level are different on those days?
Maybe...it just me ........hallucinating
