Emotiva DR-1 - Differential Reference Balanced Monoblock Power Amplifier

The ultimate in HiFi system amplification is high powered Monoblock amplifiers running in full balanced configuration. Each speaker has its own amplifier and each amplifier has it's own dedicated power supply. This configuration gives the ultimate in power, current delivery and absolute stereo separation. The massive 3kW power supply in each Emotiva DR-1 differential Monoblock delivers an abundance of power and dynamics that will easily drive even the most inefficient speakers to realistic levels. We have often paired Emotiva power amplifiers for breathtaking results with speakers such as Martin Logan Electrostatic panels and Magnepans (Maggies) which are both notoriously difficult to drive properly... of course the DR-1 can drive nearly any speaker to stunningly dynamic levels.

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 thevery 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 XPA-DR1 is designed, assembled, and tested in the USA, where we use the finest materials and latest technologies to bring you world-class products. Each Emotiva amplifier is carefully designed with premium components to deliver a stunningly capable, reliable, and refined system and comes with a 5 year warranty.

The Power Supply: The Foundation Of A Great Amplifier

In 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.  

The Latest In A Long Line Of Great Amplifiers

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-DR1 reveals every nuance of your high-resolution music sources, and it has plenty of power to drive even difficult loudspeakers with absolute authority and control.

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.

The 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.
