Closed back headphones and Focal


Hey folks, I am beginning to research closed back headphones. My primary use will be when family is still awake and sharing space so that speakers are off limits while the sound infiltration from my open backs is Less pleasurable .  Secondarily, if I find a good sounding set of cans that do well at passive isolation, I might consider them over ANC for travel. 
I also have an opportunity for a tremendous deal on the Focal Stellia. Does anyone have experience with them or suggestions for other closed back headphones?

I have the Stellia over here.
It's my first closed back.

I'm coming from HiFiman Arya.
I still have the Arya.
I'll post impressions eventually...
I'm very interested too.   I have Arya's (love them) and thinking of getting a pair of Focal closed (Celestee) just for variety.  
I have the Audeze LCD-XC, which are great (but yes, they're heavy) and I like them for private listening. They're not as transparent as my Stax 009 phones. The other choice that has been mentioned, and I agree with, are the Fostex 900s. I heard them at a stereo show and liked them a lot.
