So this wek I've tried the TDK BA200, the PFE 232 and the CK100Pro. As of this moment, the PFE232 are going to be the ones I stick with. The CK100Pro, while good, didn't seem worth the additional price over a used set of CK10s I could buy, nor did I absolutely love their sound signature. The TDK's will probably be kept and used as my gym/portable pair, as I quite enjoy their more laid back (though at times muddy) presentation. They also fit me well, which is a plus. The PFE232 just seem to be the best sounding of all four of the IEMs currently in contention and will therefore stay as my personal "flagship" IEM.
I have a few more IEMs I'd like to try, however. They include: Sony EX1000, JVC Fx700, V-Sonic GR07, Rhapsodio R^2, PFE012, PFE 122, PFE 112
