It's a shame what happened to the workers in that factory.
Regarding the claims of quality, I have no doubt whatsoever as to their validity. That's the thing that a lot of customers don't get to see in regard to the Chinese high-end audio manufacturers.
Several years ago, I imported an even larger Chinese high-end audio brand. The quality of their gear was so poor it defies description. There are just too many examples to list, but a few happen to stick out as noteworthy:
1) In my initial order, I received 10 of one of their CD player models, 8 of which were bad right out of the box
2) One run of their turntable motors ran backwards. I figured they'd be perfect for Led Zeppelin's Stairway To Heaven
3) I once received a pair of their "reference" monoblock amplifiers, where one of the amps not finished, and was missing a bunch of critical internal parts
Beyond this, a friend of mine, who is one of the more well known dealers in the country, and I got together for lunch two weeks ago. He told me an anecdote about what's probably the largest Chinese high-end audio company. He needed a bunch of their DACs, so he visited the importer, who is local to him. The importer always opened each box, as he had to test every unit to see if it worked or not. Anyway, it took them most of the day to round up his order, as more than 50% were defective right out of the box. Scary.
