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.

The Power Supply: The Foundation Of A Great Amplifier

In amplifier design, everything starts with the power supply. The XPA-DR2 features a custom-configured version of our 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. Our cutting edge SMPS offers the dynamic attributes of a classic transformer-based design with none of the drawbacks. Like the best transformer-based power supplies, our 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, our SMPS is lighter and more efficient; it’s also fully regulated, which ensures optimum performance under a wider range of load conditions.  

Class A/B Sound Quality Meets Optimized Class H Efficiency

The Differential Reference™ Modules in the XPA-DR2 each use utilize a matched pair of amplifier modules, each of which features our fully analog Class A/B output stage, and our highly regarded Soft-Switch™ Class H power supply topology, which increases their efficiency significantly without compromising the audio performance you’d expect from an Emotiva amplifier. The output stage in each operates on a lower supply voltage at low power levels to minimize quiescent power consumption and standby power losses, instantly switching to a higher voltage rail when needed to ensure the signal passes cleanly and without clipping. This process happens on a continuous basis in real time, allowing greater overall efficiency, cooler operation, longer component life, reduced power consumption, and increased reliability.

We try and keep on top of our pricing, but it's a mammoth task for one person. So, if you see this product offered cheaper elsewhere, or you are offered it for less elsewhere (proof will be required) and you feel like supporting an extremely independent retailer, do get in touch and we will do our very best to match or beat wherever we can. We can't promise to do so, as there may some extenuating circumstances where we just wouldn't be able to, but we'll always do what we can.

Needs to be like for like - new for new, ex-demo for ex-demo, same colour and specs etc.
