I'm looking for some IEMs to replace my Sleek Audio SA6s. Budget is $200-250 shipped (but I can go up to ~$300 for the right deal), use will be split between at home and commuting to work so I need decent isolation, and I'll be listening to a mix of rock, electronic and rap. In terms of sound signature I'm looking for something similar to the SA6s (ie mid-centric to warm+sweet), but I'm open to anything that isn't cold and analytical or overly bass-y. Good unamped performance is key as well, as I'll be running them straight from my old first-gen Zune or Nexus S when commuting.
Finally, Build quality/warranty is a priority. I take good care of my equipment but accidents happen, and between my SA6s' less-than-durable construction and a family member's TF10s recently biting the dust I'm looking for something I can use day-in day-out for years without worrying about them being turned into $200+ earplugs. In that same vein, a replaceable cable is a big plus.
I'm currently leaning towards either the Ortofon e-Q5s or MTPCs (big thanks to ClieOS and ljokerl for their threads). I'd prefer the Ortofons as I find the MTPCs to be more than a little gaudy (and after years of telling people "monster cables=monster rip-off, it's hard to wrap my head around dropping $200+ on their earphones), but the MTPCs have a hell of a warranty and I like the pile of accessories it comes with (I've never really been able to find the right tips for my SA6s and hate the idea of $200+ earphones being hampered by the lack of proper-fitting tips that probably cost the manufacturer less than $0.10, so the big selection is welcome).
Other models I'm considering are TF10s (unfortunately I never got the chance to really experience my family member's pair, but he loved them and the replaceable cable is a plus), GR07s (I keep reading the build quality is great but they always look cheap in pictures, and the price seems to be creeping up from the old $150-170), SE215s (the price is right and I like the replaceable cable and olives, but the sound quality might be a bit below what I'm looking for) and Westone 2s/UM2s (can't get a good read on these either way -- seem to be very love-it/hate-it). I've also just found that the Audio Technica ATH-CK10s are still available and mostly like what I've read, but they're a little on the pricey side and sound like they might be a little on the cold-sounding side.
Any help/suggestions/recommendations would be greatly appreciated.
