Even when I finally found a tube combo that seemed to compliment both cans, it would take a while for me to adjust to their different signatures. It used to take me a few days to make this adjustment, and during that adjustment period the HD800 would sound thin and dry in comparison to the warmth and lushness of the LCD2.1. Conversely, when switching to the 2.1 after the 800, the highs would sound rolled off to the point of missing detail, and the mid-bass was overpowering the rest of the spectrum.
Now that I have become more "psychacoustically adjusted" to (or more "intimately familiar" with) them, my brain has seemingly completed its learning curve and the adjustment between the two headphones happens instantly. I used to try and stick with one or the other for weeks at a time to avoid the unpleasantness of the adjustment period, and now that is no longer necessary.
Good thing because I really like variety and hate using any kind of equalizer. I moved my BBE hardware EQ to my desktop for easy access weeks ago and haven't even engaged it yet.
