    Audiophiles will appreciate the detail and resolution from the ultra-wide 1.5 Hz to 70 kHz bandwidth. Professionals will love the abundance of effort­less power. Characterized by a solid and taut low end with fully developed shimmer in the top extremes, Powerbloc2 is one of the most versatile refer­ence grade amplifiers ever.

    The benefits of multi-amplication are inarguable; lower intermodulaton, greater headroom and freedom from harmful clipping. Yet concerns over cost, bulk and complexity have prevented users from enjoying these sub­stantial advantages. The Powerbloc2 can be used in pairs with Legacy Audio's DSP based processor/crossovers to raise system performance to a new level. They can also be used in pairs to biamp passive loudspeakers.

    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
    • Huge dynamic range

    Stable into low impedances, the Powerbloc2 achieves high output without bridging and is exceptionally quiet. No transformer hum, fan noise or long waits after power cycling for stabilization.

    The Legacy Powerbloc2 provides serious power... for serious listening.

    Recommended Cables: Morrow Audio SP4 or higher level speaker cables cables are excellent for this product.
