I guess that the answer re quality is to always try things out yourself rather than rely on secondhand opinions, even on Beoworld, or, for that matter, a manufacturers reputation.
Even when quality is high, most things I buy seem to be stamped 'Designed in --------- , Made in China."
The crowd funded Olive One was widely advertised as being made in the US before it actually appeared with a 'Made in Taiwan, Designed in San Francisco' label. The only people who have gained from this short sighted manufacturing approach are banks and shareholders.
Anyway, price aside, I personally think that the H6 does a very adequate job with my particular audio set-ups.
