I've heard that Valhalla 2/Crack amplifiers works perfectly with HD700, but what about lehmann Rhinelander?

The problem that my weights are quite accurate. 17 gramms are too big fault.

I've used Grado RS2i for 4 years before HD700 and I must say that HD700 have much more cleaner sound. Basses are deaper, mids clearer but highs are not so vibrant as in RS2i. Also there is a real problem with sibilants in female voices. That what I was able to hear in 2 days of usage.

I've just bought hd 700, and I wonder did somebody weighted them? I've found that mine weights 287 gramms instead of 270 as specified at site. Could it be that mine is fake?
