I currently have SE310's, and they are my only point of reference. The cables are shot, so it's time to upgrade. I'm looking for an IEM that retains the detailed mids of my SE310's, but has a little more bass impact- nothing on the level of being bass-centric, but a little more "boom" in the sub bass area. With the 310's, mid bass is fairly good, but drums just have very little substance and don't carry.
I'm open to other suggestions, but the three mentioned in the title are on my short list because they all have replaceable cables.
By the way, I tried the Introductions forum with this post http://www.head-fi.org/t/686590/looking-for-iems-to-replace-se310s, but after all day and no replies it's nearly buried to the second page so I thought I'd give this forum a try.
