I am not one to give up very easily. I've had these Edition 12 for a year and had tried multiple sources, headamps, tubes...you name it, I had tried it and to no avail when it came to large orchestral works, which always sounded diffused, veiled, and as dull as dishwater. Yesterday I got an idea: could it be that I am not wearing these headphones the right way. Well, it seems like I finally stumbled with the truth. It turns out I have a rather smallish head and the headphones never seemed to clamp my head the way others did...they were so loose that they were always kind of slipping off my head. I decided to bend the metals holding the cups (carefully, so as not to break them) inward to make the clamping force stronger against my ears. What do you know. Now these sound like a completely different set of headphones. The veil has lifted. The orchestra now sounds the way it is supposed to sound. The treble can be a bit "too happy" at times, but treble better be there with classical music, which is almost exclusively what I listen to. Now the ED12s sound like major league headphones. Are they better than the HD800s and T1s? Well, not quite, but at least now they are in the ballpark. Are they too expensive? most definitely, but now they sound like a $1000 pair of headphones rather than a $300 pair. These are still much better with smaller ensembles than with big orchestral fare, but now I can see what Sorrodje was talking about, which I couldn't quite get before my serendipitous finding. I was strongly considering selling them to Wolfz, but now it looks like I am keeping them because I kind of like them for a change of pace since they don't sound anything like my other headphones. There is now a silken, elegant, velvety quality to them that I quite like. By the way, the best way to listen to these is to place the ears as far and upward inside the headphones as you possibly can. The more to the front and down the ears are inside the cups, the more trebly and unpleasant the sound becomes. These headphones are so picky with regard to the positioning of the ears inside the cups that they have to be the most frustrating headphones I've ever owned...but once you discover the happy zone, you're in business. Operatic voices sound just sublime (i.e., Jose Carreras and Montserrat Caballe in the famous 1976 Tosca recording sound amazing!). Great headphones for opera. Not the best pair of headphones the world has ever seen, but now I am quite happy with them. Sorry, Wolfz. Still, I wouldn't recommend them to anyone who is not willing to have a major headache with then in the process of discovering its possibilities. Looks like Sorrodje and I will be smoking the pipe of peace from now on!!!
