Sherwood,
Since you have a Lambda and K701, I think you can give a good comparison of a higher end dynamic to a stat.
As to your 5 points
1. They aren't the only brand with bad nomenclature, especially if you include vintage, which every one does for Stax. There have been many threads asking what the difference is between the many versions of the K240 for instance. AT is pretty bad too except that you can tell if the cup is wood if the name has a W, or leather if the cup has an L.
2. I'll give you that the Lambdas and Sigmas aren't everyone's cup of tea, although I don't mind the look. But then I use floats at work so I'm biased. Other than Lambdas and Sigmas, I doubt too many people would object to the looks.
3. It's easy if your cheap like me, what ever you can get cheap.
which means vintage normal bias, or SR-3 clones.
4. I have that problem with most headphones and I don't have large ears. Of the headphones I own, the only ones my ears don't rub against are the DT880 and HD580.
5. This must be a problem with the Lambdas because it's not with my Gammas.
