The Emotiva XPA-DR3 Differential Reference™ is Emotiva's flagship 3-channel audiophile power amplifier, engineered for uncompromising performance in premium home theater and high-end stereo systems. Designed to power the Left, Center, and Right (LCR) speakers with exceptional authority, the XPA-DR3 features a fully balanced differential amplifier architecture, delivering outstanding dynamics, ultra-low noise, and remarkable sonic accuracy.

Each channel utilizes dual differential Class A/B amplifier modules, powered by a high-efficiency regulated Switch Mode Power Supply (SMPS) with Optimized Class H™ technology. This advanced design delivers an impressive 450 Watts RMS per channel into 8 ohms and 600 Watts RMS per channel into 4 ohms with all three channels driven, providing enormous headroom for demanding speakers and dynamic movie soundtracks.

The XPA-DR3 offers both balanced XLR and unbalanced RCA inputs for maximum system compatibility. Its fully floating differential output stage, gold-plated 5-way binding posts, and microprocessor-controlled protection circuitry ensure superior performance, reliability, and protection against overheating, short circuits, and overload conditions. Designed, assembled, and tested in the USA, the XPA-DR3 is built to deliver reference-level sound quality for the most demanding audiophiles and home theater enthusiasts.
