I'll definitely give it some thought, as it will be at least a week or two before I buy anything. My main concern is with class coming up, I would like to acquire a decent portable amp (although many people say the eph-100's or dunu's dont need). I happen to be blessed with a $2000 desktop amp that has been laying around my house forever, but it's not like I can carry that cinder block around in my backpack. My main concern is well, other peoples opinions. I was so confident after reading up on them for a month that the Turbine Gold's would suffice my every current IEM need, but I either received a defective product or I was mislead. Things appeal to everybody in different ways, and I really just wish I lived in an area with a broader range of products to try out. If I go to AT's office, I'll see how that goes and probably decide from there.
If you listen with an iPhone from 4s to 5s you don´t Need an amp, not only with EPH-100 or Dunu´s, I use mainly Sennheiser IE80 and Grado GR10, straight to the phone and it works brilliant, I also have the EPH-100 and you can´t go wrong with them, the Dunu`s may look the better alternative if you find the extra´s important. The EPH-100 is not a bass Monster but all is there when you Need it, I listen mainly to prog-avant rock , like Primus, Chrome Hoof, Magma, classic Yes, where the bass is in a somethimes dominant role, and you all get it from the Yamaha´s, Later you can also think of the AK10 dac-amp for some extra bottom,better Separation,in short the AK10 makes everything a Little better than your phone does, but starting with the Yams or Dunu´s will not dissapoint you.
