Your experience parallel's mine! I thought I was the only one!
I have been rotating four different headphones - one week per headphone - and like you more because I appreciate the sound rather than feeling obligated to listen to them all. During the first two days of listening to a newly rotated phone, I am unable to fully enjoy the music. I think it is because my mind and my ears are still hanging on to the memory of the last headphone that I just used. This is especially true when I use the LCD2 after the T1. The change in characteristics is just so big (in relative terms of course) that my mind struggles to re-grasp the signature.
I've now managed to find a rotation that allows me to enjoy the music while at the same time minimizing the adjustment time. It used to be 2-3 days, now, it takes me only a few hours.
Has anyone else experienced the same?
Also yes the T1's rock!
