Legacy Audio has announced a four-channel follow-up to the Powerbloc2 stereo amplifier it unveiled last fall.

Priced at $2,950, the Powerbloc4 boasts an “ultra-wide 1.5 Hz to 70 kHz bandwidth” and is rated to deliver 4 x 325 watts into 8 ohms or 4 x 650 watts into 4 ohms. The amp is designed to achieve high output without bridging and is described as “exceptionally quiet.”

Dynamic range specs out at 117 dB and total harmonic distortion (THD) at 0.005 percent at rated output. Features include gold-plated binding-post outputs and balanced XLR inputs in addition to a set of standard RCA inputs.

The amp is relatively low-profile, measuring only 3 inches tall and 14 inches deep with a standard 17-inch width; it weighs 15 pounds.

“Numerous refinements to Class D topologies in recent years have resulted in improvements that not only match the neutrality of other high end designs, but actually exceed typical performance parameters in several ways: high damping factor, low output impedance, wide bandwidth, and huge dynamic range,” according to Legacy.
