DC 9K WITH HER PANTIES DOWN :()

[8ight]

Just because the board and layout look the same does not mean that the components are the same. One could have better part used than the others. I dont know enough about this to tell you what could be different, but I do know that this is the case with most amps that look the same. This is the reason that amps may look the same but have different prices.

Generally it's capacitors and FETs, same thing applies with computer power supplies where there's a billion brands and they're all made by about six big companies, all the consumer ones are made by four. Everything else has to be to spec or it won't fit on the board. Just means higher failure rate and lower ripple suppression, efficiency, output... again, same as with all DC power supplies. Has a big impact on the "cleanliness" of the power, too, so to speak.
