Emotiva XPA DR3 3-Channel Amplifier

Full Description
The Emotiva XPA-DR3 is a high-powered three-channel audiophile power amplifier that combines the exceptional accuracy and finesse of a true balanced differential design with the power you need to deliver musical crescendos and movie special effects with stunning realism and impact. Whatever your listening preferences, the XPA-DR3 will give you the combination of detail and power than only a fully differential amplifier can provide.
The XPA-DR3 features three of Emotiva's Differential Reference Amplifier Modules, and is the ideal choice to power the critical front three channels of an absolutely awesome surround sound music or home theatre system. The XPA-DR3 delivers 450 watts RMS into 8 Ohms, and 600 watts RMS into 4 Ohms, all three channels driven, with less than 0.1% THD.

Most experts agree that, if you want the absolute best sound quality and technical performance, you should use dedicated separate components. Because Emotiva's power amplifiers are designed for a single purpose, they 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 Modules in the XPA-DR3 are each 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, Emotiva are able to achieve even lower levels of distortion in the XPA-DR2, resulting in remarkably transparent sound, with unprecedented smoothness and clarity.
When you put it all together, the XPA-DR3 is simply the finest three-channel amplifier Emotiva can devise, and they are sure youll be as impressed with its performance as Emotiva are.
