Emotiva XPA-1 Differential Reference Mono-block Power Amplifier

Effortless power. Performance. Sound. A true reference level amplifier.

You know that sweet spot all amplifiers have? That magical level where things are rich, full, but still a bit relaxed? The amp is in its comfort zone, open, but not overworked. What if you could find that sweet spot at practically any volume level?

It's all about control, and the XPA-1 is a control freak. 500 watts RMS into 8 ohms, 1,000 watts RMS into 4 ohms. All the performance you'd expect to see from an audiophile reference level amplifier. But what about the sound? Big...expansive...powerful...and yet very refined...and defined. This is what you get when you have control.

Mono-block amplifiers have typically been company flagships. They define the ultimate expression of a company's approach to design and construction. The XPA-1 amplifier puts our ultimate expression within your reach at market-shattering prices.

Our commitment to build quality, superior design and ultimate performance is reflected in every facet of the XPA-1. Effortless. Period.

XPA-1 REVIEWED AT HOMETHEATERHIFI.COM:
"They are some of the best amplifiers I have ever heard, period, and they will have to be be pried out of my cold, dead fingers."
