Has anybody bought or heard a Chinese knock off amplifier?


There are a lot clones coming out of China and power amplifiers seem to be along for the ride.
Mark Levinson, Goldmund, and Accuphase are some of the big names I see replica’s being advertised for sale. These replica’s range in price from $500-$2000. My curiosity every time I see these always is do they even sound like the brand they are trying copy? Another thought that comes to my mind when I see them is, are they even safe or reliable. I myself wouldn’t touch one of these, but that’s me. Has anybody heard one? If so it would be interesting to hear some opinions regarding these amplifiers.

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.

Are there really that many fires in China?
