I'd be interested in hearing more about the UE-Reference / ES-5 / JH-13. I've only had a chance to hear the JH-13 and JH-16 universals and thought both had a little too much bass around 50hz for the large amount of electronic music I listen to. The UM3X and no.34 customs have made me wary of dealing with Westone again, but I've never had bad service, so they aren't completely off the list yet.
