Hi everyone, Its a little over 2 years now since I bought the SA6 after some great advice from people on this site (tstarn06 in particular). I love these earphones and their exceptional smoothness (I can't really call it anything else). Overall, the bass was a little light but well defined and the bass++ mod kept me happy for a while. The only problem I've ever had with them was the horrendous cable quality which forced me to buy 3 replacements since august 08 and now the last replacement has given way as well (A more minor thing was the fact that these aren't very sensitive IEMs at 110 dB/mW). Anyway, I decided that it was time for an upgrade to something better that improved on the SA6 (better bass, cables) but retained its overall smoothness. My budget is about $500 and I will not be able to audition any of the headphones. I listen to all kinds of music so something that works well for a variety of genres would be good. If I had to pick a genre that I listened to primarily, it would be House and Classical/Orchestra (like movie themes). Soundstage is important for me and so is bass that is clear but definitely more powerful than the SA6. As I have said before, I'd like the IEMs to retain the smoothness of the SA6 and IMO their non fatiguing nature as well. I'm looking to choose between the following and am open to other suggestions. I'm not looking at the westones as I've mostly read that their soundstage isn't too great. Earsonics SM3 (I've heard tons of great things about these and they're my first choice right now because of their popularly perceived widest and 3D sound stage and the way they apparently work well for most types of music) Ortofon e-Q7 JVC FX700 Sennheiser IE8 Audiotechnica CK10 or CK100 UE TripleFi I will be running these ampless from my Samsung Galaxy S (which has a built in Wolfson DAC) and in future -- a modded+Rockboxed iRiver H120 (I currently have it in stock condition). I also have a Fiio E5 (which seriously helps the SA6 right now) Any suggestions are welcome. I'm looking to buy something roughly before christmas so there is plenty of time to analyze and discuss the possibilities. I'd in particular like to hear from people who've owned both the SA6 and any of the so called top-tier IEMs and if they could tell me which ones are in particular better than the SA6 and are worth the money spent on the upgrade. I'd also like recommendations from people regarding which IEMs synergize well with the Samsung Galaxy S line of phones (vibrant, captivate, epic 4g etc). Thanks in advance for the responses.
