keep in mind where you live. In the USA, the JMLabs are a hard sell. Fantastic, but your paying for cross Atlantic shipping. In Europe, they are hard to beat.
The Kharma's sound fantastic. Fantastic. But, I hate them. As stated above, this isn't really an even set, except for maybe the WP7 and the Aerials (extrapolating what I hear in the 10Ts and applying the implied design differences. How's that for vague!).
