XPA-9 Gen3 Nine Channel Power Amp



Only 1 left!

The new XPA-9 is a nine-channel audiophile quality power amplifier. The XPA-9 is populated with five of our High-Powered Single Channel Modules, and two of our Stereo Modules, for a total of five high-powered channels and four lower-powered channels. This combination is ideal for a surround sound system that is used for both music and home theater listening, and includes height speakers.

In a 5.1.4 system, the front speakers and surrounds are powered by high-powered channels, while the height speakers are driven by the lower powered stereo modules. In a 7.1.2 system, the front speakers and side surrounds are powered by high-powered channels, while the less critical rear surrounds and height speakers are driven by the lower powered stereo modules. Even though the channels differ in terms of maximum power output, they feature perfectly matched electrical characteristics, and the same superb Class A/B sound quality.

The XPA-9 is perfect for powering:

  • A 5.1.4 Dolby Atmos or DTS-X system

  • A 7.1.2 Dolby Atmos or DTS-X system

  • A 5.1 channel system with two additional pairs of speakers in other zones

  • A 7.1 channel system with one additional pair of speakers in another zone

  • A 7.1 or 7.2 channel system that also includes two pairs of smaller speakers in other zones

The power output capabilities of the various channels on the XPA-9 were optimized to provide the best sound quality in real-world listening conditions; the main channels, which are the most critical for both dynamic music reproduction and crystal clear dialog, receive the most power.

5 x High-Powered Single-Channel Modules
2 x Stereo Modules

Power output (Stereo Modules):
65 watts/channel RMS into 8 Ohms; two channels driven
100 watts/channel RMS into 4 Ohms; two channels driven

Why You Need A Dedicated Power Amplifier
Most experts agree that, if you want the absolute best sound quality and technical performance, separate components are the way to go. Our new Third Generation XPA series power amplifiers are all designed from the ground up to perform a single critical task – to accurately reproduce every detail and nuance of your music. By focusing all of our efforts on that one goal, we’ve been able to design an amplifier that performs its job with remarkable precision, and avoids most of the compromises that limit lesser designs.

Experience Meets Cutting Edge Technology
When we set out to design the latest version of our XPA series of amplifiers, we analyzed everything in every amplifier we’ve ever made, from front to back, inside and out. By combining years of design experience, with a thorough understanding of recent advances in audio technology, we were able to determine several areas where we could improve on our previous designs. After carefully weighing all the options, we kept the best features of our previous models, added some new technology where we determined it would actually deliver significant improvements, and optimized several operating parameters to ensure that it would all work together flawlessly. The new Third Generation represents a significant improvement for our highly acclaimed XPA series of amplifiers – and delivers improvements in both technical performance and sound quality.

All of the models in our new Third Generation XPA amplifier family are designed to reproduce today’s high definition movie sound tracks and music sources with awesome realism, amazing finesse and precision, and without the slightest hint of strain or signal compression. They deliver a listening experience that is far above anything you can achieve with multi-purpose components like receivers, or with other amplifiers in their modest price range. We’re talking about real-world power and fidelity that you can immediately hear and appreciate.

Regulated Switch Mode Power Supply (SMPS)
One of the main limitations with traditional amplifier designs has always been the power supply. Until recently, a power supply that could deliver enough current to run a modern high-powered amplifier required a bulky transformer and large filter capacitors. While these traditional power supplies delivered good performance, they were heavy, expensive, and inefficient. For years, precision components like preamps and processors used regulated power supplies, but regulated supplies powerful enough to be used in large amplifiers remained complex and prohibitively expensive.

Thanks in part to recent advances in power supply technology we’ve finally overcome this limitation. One of the design enhancements shared by all of our new XPA power amplifiers is our new, specially designed, high current, switch mode power supply (SMPS). Our powerful, intelligent new power supply offers all of the benefits of a classic transformer-based design, but avoids virtually all of the limitations. It can deliver over 3 kW of fully regulated power, which ensures optimum performance under a wide range of load conditions, and plenty of dynamic power to ensure that musical peaks will never be compressed or limited. However, it’s also more efficient, more reliable, and much lighter. (Our revolutionary new SMPS has enabled us to reduce the weight of our new amplifiers by about 30%, making them easier to ship, and easier to install in your equipment rack or shelf.)
