And they say ignorance is bliss... Sundown amp use IR mosfets in the bigger amps, chinesse mosfets in the smaller amps, japanesse output transistors in the smaller amps, and IR mosfets in the output of the larger amps... It's no secret, and none of those options are inappropriate. Please do your homework before you come on here spouting garbage...the quality of the parts play a big role as well. if he's using American made parts they are going to be far superior to the chinese junk that companys like sundown etc use. therefore he is able to get better numbers. the fact that you have never even seen one also says they are better quality than others like sundown chinese crap.
Only Sundown amp made in China is the SAE-1200D, the rest of them are all Korean made, and that 99% of the good amps out there are made in Korea.
