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?

If you're in Portland, Echo Audio has a pretty good selection of headphones and they often have used Audeze headphones at great prices.  They currently have a pair of LCD-X (not closed back however).  They also have a pair of AKG812's, which are also not closed back, but very nice cans.  They are very detailed and neutral, a different sound signature from the Focals and very comfortable.
Thanks Big Greg. Yup, I have listened at Echo. Currently I need closed backs because my listening room is multipurpose. Living with other people ;) 
@switzer145 Check out the thread “Anyone interested in nearly perfection on a headphone a a great price??” here from a few days ago also in the Headphones category — the OP has nice things to say about them and references several other headphones he’s compared them to.
