The PMA-1600 is a quality, good value, integrated amplifier. It is conservatively rated for power output and other performance specs, and most of these amplifiers go to markets outside of North America mainly western Europe and Australia. It was designed in Korea and built in Vietnam by the same factory that assembled Marantz, Harman/Kardon, NAD, Anthem receivers. Also the same factory builds the majority of soundbars and BT smart speakers for Denon, Yamaha and JBL.
Just my $0.02....
