A few years ago, you’d have to pay thousands for power and finesse like this. Consider the massive toroidal power supply, 24 high-current output devices, and an elegant and sophisticated power amp design that delivers 300W into 8 ohms, and 500W into 4 ohms with both channels driven. The XPA-2 provides serious headroom, the kind that really wakes up your speakers. Enjoy the tight, controlled bass and effortlessly detailed highs.

Go ahead. Use the XPA-2 in the finest music-only stereo listening rooms, or set it up for ultimate authority and control over the front channels in your home theater. Its enhanced power capabilities will provide even more authority and control than the XPA-3 or XPA-5.

Listen to your jazz open up and breathe like never before. Hear that favorite symphony recording gain a new level of dynamics and sense of tangibility. Feel a part of the action and excitement of movies like never before. Crank up a concert and get lost in it.

It’s a beast. A monster. A gorilla. An abominable snowman on steroids. It's a rock concert in an 80 pound box. And by the way, it's also delicate, graceful, and just plain beautiful.
