After six years, I believe the cable is starting to go on my SE310's. Not wanting to be out another pair of $250+ IEM's for want of a cheap cable, I've decided that whatever I choose as a replacement must have a replaceable cable.
I'm sure this will be quite limiting, and so far I have these in mind: UE900, UM3x-RC, Westone 4R, and SE535, in no particular order. Coming from a fairly midrange set of IEM's, I'm thinking any of these should be a noticeable upgrade. Even after searching every relevant post, I'm still having trouble determining which one would be suit my preferences.
What I liked most about my SE310's was how what I believe are the "mids" were presented - opening guitar riff from Ted Nugent's Cat Scratch Fever, piano and vocals from Billy Joel's And So It Goes. My only complaint about them is that they were light on bass; they extended low enough (the very low notes from David Essex's Rock On were present), but never had much impact. For example, when the drums hit in John Mellencamp's Jack & Diane, they're just a short, hollow "thud" instead of a nice, deep, resonant "thump", if that makes any sense. It's as thought the sound of the drum just dies and doesn't get a chance to reverberate. I guess I'm looking for slightly more "boom".
I read every review and comparison thread regarding these IEM's I'm considering, and I understand that none of them are known to have overly abundant bass, which is ok. I'm not looking for anything headshaking, just more impact than I have now. Additionally, since all of the higher end IEM's are compared against each other for obvious reasons, it's difficult to interpret whether or not "light bass" for a triple or quad driver high end IEM would be the same as "light bass" for the single driver midrange IEM that I'm replacing.
I also considered the Westone 3 since I'm positive it has plenty of bass response, and I would probably jump on it if it had removable cables. Disregarding this, I'm worried that the midrange that I appreciate so much from the Shures would be recessed in these.
Thanks for the help!
