Got a pair of regular EL-8 closed about a month ago, one of the drivers got funky so I took them back to the Apple store and opted to 'upgrade' the titaniums. They look much better IMO, but the sound is really the same as running them through a portable DAC/amp (I had been using a Fiio e18). Which is a win actually because I no longer have to bring the brick with rubber bands around with me. EL-8 closed ran fine from an iDevice, but the E18 helped control things, better bass, less shouty in the upper mid/lower treble. Minor things in the EL-8s are ameliorated this way.
Cypher cable seems to be doing the same thing pretty well.
If you already have something like am E18 and don't mind the bulk/clutter, then there is nothing for you in the titanium edition unless you are just stuck on the metal aesthetic over the fake wood one. If you don't have an iDevice, obviously don't bother, again unless you are dead stuck on the looks as it does have a regular 1/8' cable. If you do have an iDevice and had previously been considering a portable DAC/amp, then this would be a good option.
I'm happy with the setup for the office and commuting. It's funny to listen to these and then my LCD3s and vice versa. You can see (hear) a lot of shared DNA in some songs and makes you wonder why anyone would buy the LCD3s, then in other songs the superiority of the LCD3s stares you in the face with authority and there is no doubt.
