Well i hope you don't expect a professional sound analysis
My ranking is a result of personal taste relating to the music i'm listening to. I wouldn't say Phantom is better than LX. But the Phantom imo is a bit more versatile. When i bought both i haven't expected the Phantom be the best choice for electronic music. That's the genre i preferred the LX over the Phantoms from the very first listening. But after more than 200h of burning in things have changed
Now i don't change from Phantoms to LX anymore when it comes to electronic. I simply keep them on the whole listening session throughout all genres. Not the same when i wear the LX.... then, after some time i feel the need to come back to this lovely, natural sound of the Phantoms. I think i prefer them over the LX because of their incredible balance and their elegance. But that's just my opinion.
The difference between Vega and ie800s is huge. I think they have not much in common despite of the fact they are both DDs. I think they complement each other very well (like the LX and the Phantoms do) I love the Vegas for Dub Step and unpretentious, bassy sound with lots of ooomph
the Senns sound more balanced. Much better for relaxed late night listening. I prefer the Senns over the Vegas when listening to Pop (Coldplay f. e.) among other things because i love how vocals sound with them and i like their smoothness.
