XPA-2 Gen3
• Audiophile grade Class A/B output stages and a massive silent switch mode power supply.
• Two high-powered single-channel modules.
• Perfect for a stereo setup or the front two mains in a home theatre system.
• Every great system starts with a great amplifier.
The power amplifier performs the simple but critical job of boosting the output signals from each channel of your stereo preamp or surround sound processor to the level necessary to drive your loudspeakers. While this may seem trivial, a really good power amp is essential to having a great audio system, because any flaws in the performance of your power amp are going to limit the performance of your entire system. Every amplifier in the new Third Generation XPA series was carefully designed to deliver superb technical performance, unsurpassed sound quality, and an exceptionally accurate and dynamic rendition of all types of music, thus ensuring that your entire system will sound its absolute best. Each XPA amplifier is modular and can be customized to provide exactly the power and number of channels you need today and expanded later if your needs change; multiple matching chassis enable you to add even more channels, or more power, for a near-endless variety of options.
