Would you say the LTD is leaner than the ADV or around the same? I'm surprised that you would say they have the same type of sound because as I understand it the SE215 is very popular and I'm not sure the ADV will be.
It was mentioned somewhere (forget where, probably some Japanese site) that the piston-looking thing behind the driver was completely redesigned, and the 215SE is clearly bassier than the normal version, both in 'thump' and sub-bass. Never took it apart, though, if that's what you're wondering.
I would say that the two are about the same in terms of thickness, but I never did an A/B. I can only say that, on first listen, I was far more impressed with the SE215SPE than I was with the ADV. The ADV may have better imaging, though?
