Just my two cents:
Without EQ the L1 sounds just bad compared to the CAL!.
It's some kind of veiled and to me, the 2KHz region has too much power, which makes it sound unnatural.
The CAL! sounds surprisingly well together with Pop-music.
Much more lively than the L1!
Comfort wise the L1 ist much better!
I think I'll sell my L1 very soon, because it can't surpass the combined power of HD800 (Jazz, Classical, Rock, etc.), HFI-580 (Games, Rock, Electro) and CAL! (Pop, Rock) in any way.
Than -after that- I'll just have to decide what to do with HD650, HD600, K701, DT880, D2000 and several other cans.
I think HD800, CAL! and HFI-580 is all I need to get the best out of all the music I use to listen to.
The L1 is no bad can, but it's also not good enough to stay.
But it's a personal matter of taste.
