Has anybody bought or heard a Chinese knock off amplifier?

I was invited to dinner at a friends home some years back, while we was sitting in the family room eating  we looked over and seen a red glow in the room, then we started to smell plastic burning, the amps was on fire!
he had purchased the amp form a web site based out of china, baking soda should be stationed near EVERY CHINESE POWER AMP, and what he found out was the amps had NO UL -Underwriters Laboratories on the amps. buy American so your home don't burn down.

"...buy American so your home don't burn down."

Are there really that many fires in China?

Long thread at AK about this:

I don't see problems of buying items being sold as clones. People know what they are buying: clones, expecting they are as good as originals, but they should not believe that those clones always work the same as the genuine. They are poor (or cheap) man's choice.
Counterfeit is a different story. People buy stuff believing they are genuine, but actually counterfeit. In this case, I see problems are on both sides: the counterfeit manufacturer and the buyers who buy those at fractions of cost, believing they are buying genuine. They hope those items are genuine overstock items (or genuine stolen goods?).
I haven't bought any clones or counterfeit yet, but I've bought a few Chines products under Chinese brands: Yaqin, Jungson, and Douk audio. They were all very good for their price, even though some had a bit of reliability issues. For Chinese products, it is a relatively safe bet if you purchase products from established companies.
