In the market for new IEM/Portable Amp

So, looking for a pair of mid-range IEMs for general listening. I'd consider myself an intermediate audiophile so, I can appreciate one pair for what it is as opposed to another. I've mulled around the subject for over a year now, considering I was counting on UE's "yearly" TF10 Pro $99.99 Black Friday sale which didn't seem to happen this year. Of my contenders are: UE 700, VSonic GR07, Etymotic HF5, Brainwavz B2, Yamaha EPH-100SL, and Shure SE-215. I've considered a few others, such as (once I have the free cash) the Westone 4R for my high end pair and the SE-535. I'm trying to stay sub-$200 with this buy. I've also seen the Ortofon EQ5 and EQ7, and would love to pick them up, but they're a little out of my range since they're semi-rare. I'm very open to the idea of using a portable amp, as well, and if some paired with an amp outclass others, let me know and with which amp(s). I listen to alt rock, indie, punk rock, classic rock, metal, a little electronic, slight dubstep, and a few other minor interests. Durability would be a plus, but not absolutely necessary. Extras are also nice. I just want an IEM that I will not regret spending the money on. Headphone and amp suggestions is what I'm looking for out of you guys and if one pair with an amp is better than another IEM with another amp/without an amp, let me know! Open to other suggestions, as well. Think that's about it. Alright, guys. Get to it!

I should also note that currently I'm using a pair of Koss PRODJ100's, if that makes any difference. I'm happy with their sound, especially considering my opinion that they are "Beats-killers".
