Has anybody bought or heard a Chinese knock off amplifier?

The OP asked about knock-off products, not products made in China! Apples and Oranges!

Knock-offs can be products that have a confusingly similar overall appearance to the copied products but knock-offs do not contain any identical logos or federally registered brand names. Fashion knock-offs are legal in the U.S. but a counterfeit is not.

Its all Trumps fault !

hiendmmoe  I must respond:  Yes, China is beginning to sends rovers to extraterrestrial bodies.  There are no parts available to US (or British, etc) designers that the Chinese cannot get, especially since they manufacture for many American companies.  You would have to be racist to think they cannot do this.  Admittedly, at one time I fell in this category by thinking Japanese cars and racers would ever compare to AMURRIKUN, but we live and learn.  We should not wonder if the Chinese can, bur why they do what they do.  When a Chinese product is truly good, the company will proudly market it.  If it is a POS, it will have someones else's brand on it.   

cid194532 posts02-05-2021 4:46pmI’ve never heard of well known brands like Luxman or Accuphase knockoffs. Seems they would be easy to spot or the price would be the tipoff. The Chinese are making some excellent amps at very good prices. Their designs look old school and nostalgic.

The price is always the 'tip-off', but only when new. After the piece reaches the secondary market, all bets are off. This is when unscrupulous resellers crank up the selling price to that level at which an unknowing buyer can't believe his 'good fortune'.

here is a copy
