I want to write a review about these headphones since I've had them for over a week now, but it's going to be a challenge. I can really only compare them to a fleeting moment of a trial of an LCD3 and a Stax SR-007, and the rest of my experience is total mid-fi.
Hmmm, I'm going to spend some time to continue gathering and forming my thoughts. If I wrote a review now I'd just be gushing praise and while that's fun, it's not terribly useful to read.
In short, though, I don't plan to upgrade for at least another year. I'm not sure upgrade is still the right word for a new purchase at this point, either. These headphones have changed my perception of what personal audio can be.
