The XPA-9 is powered by a high efficiency, audiophile grade, Switch Mode Power Supply (SMPS)

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.

We try and keep on top of our pricing, but it's a mammoth task for one person. So, if you see this product offered cheaper elsewhere, or you are offered it for less elsewhere (proof will be required) and you feel like supporting an extremely independent retailer, do get in touch and we will do our very best to match or beat wherever we can. We can't promise to do so, as there may some extenuating circumstances where we just wouldn't be able to, but we'll always do what we can.

Needs to be like for like - new for new, ex-demo for ex-demo, same colour and specs etc.
