If you're in the midst of planning a little soirée over the Christmas period, or are generally just a bit of an audiophile, then we're giving away the perfect piece of kit this week. The sleek, minimalist Cyrus One amplifier features four line level inputs and two, 100W outputs to power your speaker setup at home. And if the amp's aptX-compatible Bluetooth connection isn't wireless enough for you, our friends at Cyrus Audio are throwing in a Chromecast Audio and three-month subscription to Tidal's lossless 'HiFi' streaming tier to boot -- a bundle that's currently available at various specialist retailers for a limited time. Get involved in the giveaway by turning your attention to the Rafflecopter widget below, and all we ask is you give the rules a quick glance before you do.
