Hi. I'm at a bit of a crossroads. I have lived with a pair of IE8's for several years and finally became exasperated with their very coloured sound. I then bought a pair of ACST15's. On their own I find them rather "dry" or thin. With a Digizoid bass enhancer they sound great. But I am back to a coloured sound. I am now seriously thinking of going for broke and buying a pair of Earsonics SM64's. I did briefly hear these when I came to Hi Fi Headphones with a friend for a demo. For the price I would hope that the 64's are something pretty special. My thread is titled disillusioned as that is what I am becoming with higher end IEM's. I understand that nothing is perfect and compromises are made when creating the headphones but I am very surprised by the rather extreme nature of these compromises. It is as if the designer expects us to accept some pretty terrible shortcomings in exchange for high performance in a particular area. Are the Earsonics likely to be another "Marmite" experience? Is it too much to ask that a pair of headphones at this price point has no obvious flaws? Sorry for the long post. I have bought all my headphones from you and will continue to do so. Unless I decide to give up and start collecting thimbles or something!
