My personal preference ranking chart, most recent edition:
The top two rows constitute my "S tier"-- but the IEMs on the top are there because they dovetail with my personal preferences or flat out knocked my socks off in some extraordinary way. The reason Jewel isn't on top is that I've only demoed it briefly and haven't spent enough time with it to really have a full sense of it.
In other news since it's officially summer I thought it would be a good time to revisit the "Watercooler charts". At the beginning of spring I asked everyone for the top 3 IEMs in their lives at that moment. The results were very interesting. Perhaps we could make this seasonal affair...so without further ado, what 3 IEMs own your heart at the moment? Criteria for selection is entirely up to you.
My votes:
1) Supermoon
2) EXT
3) Annihilator
