Turning on one turns on the other, if you use the remote. They ship with identical remotes that have sections for each particular model - meaning that if you only buy one, you'll have a whole section of your remote that is utterly useless. The CXN and the CXA80 were designed to work together. The thing is, these aren't just two components that happen to share a parent company. It's a $799 80 watt integrated amplifier with included DAC, and it will work with any existing speakers or components you happen to have. As we explain in more detail below, it handles just about any audio source impeccably, and will happily slot into an existing system. It's entirely possible to use the $900 Cambridge Audio CXN (V2) as a simple music streamer, connected to an amp and DAC of your choice. We'll be showcasing more alternatives in our roundup of the best music servers, coming soon. In this review, we break down the sound, design, packaging and accessories, specs and more of the CXN (V2) and CXA80. Cambridge Audio's CXN (V2) streamer and CXA80 amplifier may retail as separate products, but we've never seen another pair that work so well together. For the first, time, we're reviewing two products at once.
