XPA-3
Three-Channel Power
Amplifier
Supercharge your home theater with
this overachiever.
The typical receiver is a series of compromises. It's give and take - size, cost, power, performance - you can't have it all. But in order to deliver a lifelike, clear and engaging cinematic and musical experience, you need real power—and lots of it.
This is where the XPA-3 comes in. Use the XPA-3 to power your left, center and right speakers, and let the receiver take care of the surrounds. You'll notice an amazing improvement in detail and dynamics, and an exceptional improvement in the clarity and natural presentation of voices and instruments. Wait until the action starts, and then... hold on!
Like all of our X series amps, the XPA-3 is a brute. When we say 600 watts, we mean 600 watts. That's the minimum output power of the XPA-3, with all channels driven. No excuses. Just real, honest power.
For even more amazing performance, combine the XPA-3 with an XPA-2 for an absolutely knockout 5 channel system.
