Are these fake?

It is also worth remembering the Chinese do their luxury goods shopping in branded shops in Europe and the USA.  They know full well if they use the shops in China they are likely to get a fake.  On some occasions a completely fake branded shop has been established and open for a few hours or days offering 'discounts'.  Shades of 'The Sting'.

Like I said - the wild west, or perhaps east.

On fake Rolexes.

Many years ago I was sitting by the pool in Thailand with a friend.  He had shown me his new 'Rolex' and I simply said it was nice.  A little later we decided to cool off in the pool and he started to remove the watch.  'You don't need to take that off, it's waterproof to 1,000 feet'.  Oh, this one I do!'

Hi radblue

This is just one of the many dangers of doing business in China.  The over-production scam has been going for years and will continue.  If said amp retails for $10,000 and can be manufactured as additional numbers on an existing line for $750, there is a temptation most cannot resist to bang out some more and sell them at $6,000.  Nothing can be done, China is the wild west, there is no rule of law or legal system in the Western sense and in any case the Chinese courts will always favour their own.  Many businesses opening up in China have been cheated.  I know of one international blue chip that simply closed their factory in China and walked away.  They were being cheated so badly and couldn't do anything.

Moral.  We need to try to reduce our business with China so they realise they need to clean up a bit.
