Robm321: Understood on head-fi (didn't realize, and yes, it's a bit daunting). I am glad that I helped. It "sounds" like you know your headphone/amp stuff, too, so I am glad to have been of service on the IEM end.
I can also add that I have never listened to the Etymotics, but they have a huge fan base...from what I have read, they are more detailed, have more high's, and are less comfy than the Shure's. Folks say the Shure's are more musical and the Ety's are more analytical. It seems that folks who like rock (like me) go for the Shure's and folks who like classical, go for the Ety's.
Since you are familiar with head-amps, and you travel, which means carrying a portable head-amp should not be an issue, I do recommend getting a portable headphone amp, even if it's just a toy to compare and contrast. It will make a difference with whatever IEM you get, but I must say, for me, the Shure e4 amped is really good: fast, musical, deep/tight bass, and strong highs and mids.
