DH is not the only one: even before seeing his video, I was alarmed by the fact that in the 2 reviews on the set's page on amazon, one from the USA said the sound is "lousy", the other one from germany says "Der Klang ist distanziert und blass" (distanced and weak, according to google)
Usually these "user reviews" are all over the place and do not agree on anything.
