XPA Gen3 DR-1 Monoblock Differential Reference Modular Power Amplifier

XPA Gen3 DR-1 Monoblock Differential Reference Modular Power Amplifier

£1,549.00Price
The XPA-DR1 is a true monoblock power amplifier, and features a single Differential Reference Amplifier Module, in a true monoblock configuration, powered by its own dedicated 3 kW switch mode power supply. The XPA-DR1 provides massive power, superb dynamics, incredible resolution, and absolute control. If you’re looking for the very best sound quality, with virtually endless reserves of power against a jet black noise floor, this is the amplifier for you.

  • Circuit Topology

    • A fully modular, fully differential, fully balanced audio power amplifier with a high-efficiency switch mode power supply (SMPS), independent, fully discrete, dual differential, high current, short signal path Class A/B amplifier modules, Optimized Class H™ power supply topology, and microprocessor-controlled fault protection.

    Audio Specifications

    The XPA-DR1 features one Differential Reference™ Amplifier Module.
