Legacy Audio Powerblock² Amplifier
“Incredible performance in a small package…at a fair price” is how Legacy Audio describes the Powerblock², the company’s first amplifier in more than a decade. Assembled in Legacy’s Springfield, Illinois factory, the amp is a dual-mono design boasting an ultra-wide 1.5-Hz to 70-kHz bandwidth and healthy power output of 2 x 325 watts into 8 ohms (or a rip-roaring 2 x 650 into 4 ohms). Ice Ice Baby: The low-profile Powerblock² is built around ICEpower Class D technology featuring self-oscillating closed-loop architecture and a robust power supply capable of supplying peak current of 30 amps per channel. High damping factor (1,000 <1 kHz) and dynamic range (117 dB) are cited as key characteristics along with low distortion (0.005% THD at rated output). Balanced XLR and unbalanced inputs are provided. Price: $1,600
