Whatever your listening preferences, the XPA-DR2 will give you the combination of detail and power than only a fully differential amplifier can provide. The XPA-DR2 features two of our Differential Reference Amplifier Modules, and is the ideal choice to power a no-holds-barred stereo music system, or to power the critical front left and right channels of an absolutely awesome surround sound music or home theater system. The XPA-DR2 delivers 550 watts RMS into 8 Ohms, and 800 watts RMS into 4 Ohms, both channels driven, with less than 0.1% THD.
In amplifier design, everything starts with the power supply. The XPA-DR2 features a custom-configured version of a high-current switch mode power supply (SMPS) - a lightweight, powerful, intelligent design capable of delivering over 3 kW of continuous power with absolute reliability and extremely high efficiency. The cutting edge SMPS offers the dynamic attributes of a classic transformer-based design with none of the drawbacks. The SMPS delivers plenty of continuous power to enable our amplifier modules to live up to their full performance potential, and plenty of dynamic power to ensure that musical peaks will never be compressed or limited.
However, compared to transformer-based designs, the SMPS is lighter and more efficient; it’s also fully regulated, which ensures optimum performance under a wider range of load conditions. The Differential Reference Amplifier Modules we use in our XPA-DR amplifiers use the same basic circuit topology as our legendary XPR series amplifiers. A unique differential input stage, with a cross-linked current source, drives a balanced voltage amplification stage, and this advanced input circuitry delivers an incredibly accurate and pure audio signal to the complementary, fully discrete output stage.
A pair of these modules work together in perfect synergy to power a single channel of one of our new fully balanced, fully differential, XPA-DR amplifiers. Together they deliver a holistic, natural, and powerful listening experience. Low-level musical details and dialogue emerge from a deep black background; musical crescendos are delivered with both stunning impact and precision. The wide bandwidth, low distortion performance of the XPA-DR2 reveals every nuance of your music sources, and it has plenty of power to drive even difficult loudspeakers. Power output (both channels driven): 550 watts RMS, per channel, into 8 Ohms, at <0.1% THD, 800 watts RMS, per channel, into 4 Ohms, at <0.1% THD. ■
