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.The XPA-DR1 delivers 650 watts RMS into 8 Ohms, and 1000 watts RMS (that’s 1 kW) into 4 Ohms, with less than 0.1% THD.The Power Supply: The Foundation Of A Great AmplifierIn amplifier design, everything starts with the power supply. The XPA-DR1 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™ Module in the XPA-DR1 utilizes 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.

Benefits Of A Fully Differential Balanced Power Amplifier

Most experts agree that, if you want the absolute best sound quality and technical performance, you should use dedicated separate components. Because our power amplifiers are designed for a single purpose, we can concentrate on ensuring that they perform that one task very well, and avoid the compromises inherent in products that are expected to perform a variety of different functions.

The Differential Reference Module in the XPA-DR1 is made up of a perfectly symmetrical balanced pair of high-performance amplifier modules. Each individual amplifier module already has vanishingly low distortion but, by connecting them as a balanced differential pair, a significant portion of the tiny amount of remaining nonlinearity is cancelled out. As a result, we are able to achieve even lower levels of distortion in the XPA-DR1, resulting in remarkably transparent sound, with unprecedented smoothness and clarity.

Finally, because the XPA-DR1 is a true monoblock, and only contains a single power supply and amplifier channel, even the slightest possibility of interaction between channels is eliminated, ensuring the best possible isolation between channels, and perfect channel separation. When you put it all together, the XPA-DR1 is simply the finest amplifier we can devise, and we’re sure you’ll be as impressed with its performance as we are.

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.
