I'm tempted to hand it to the custom IEM brigade, but even then I would be petrified of losing/damaging a $1300 investment on a bus etc.
No shortage of 'out there' would-be portable rigs on Head-Fi, but you have to ask yourself just how realistically 'portable' many of them are. Anyone who has been to a (sanctioned) drag race meeting knows that you can put number plates on a racecar, but good luck actually driving it on the street ...
I actually don't use an amp for my UE-11's for the first reason - I want my portable to be, well, portable. I've got a T4 and it's just not worth using it.
The only thing I consider using is the Fiio E1 - it can help some brighter earphones like my UE's to calm down a little bit. But mostly I go straight out of an i-device into my IEM's.
As for using incredibly expensive custom IEM's, yes, that is true, there is a risk. I took it and after four years, I paid the price about a month ago. I dropped them and one ear shell burst. I got it fixed (by a one-man business by the name of Cinepaq in the Netherlands) and bar a tiny fit issue, they are now perfect. The fit issue is being worked on right now and I expect a pair of perfect earphones to arrive next week. Great, personal service all around.
But it is an (expensive) risk nonetheless. I think it's utterly worth it - custom IEM's are amazing, easily beating anything else you can bring with you, ever.
