The Edition 8 is the top of the heap and features lovingly crafted workmanship, expect to pay big $ but expect to get a great pair.
Also on show was a pair of balanced headphones Pro 900 and matching balanced headphone amp - H101, which apparently results in the most astonishing audio reproduction .
