Some high-performance audio gear seems like it was designed a decade ago, before music downloads and streaming services became the norm. But Cambridge Audio's versatile CXN was clearly engineered with today's audiophiles in mind. Its connections and controls will optimize your favorite digital music sources. It handles the most popular digital file formats and gives them all a sonic upgrade, from lossy sources like MP3s and Spotify®, to your CD collection, to high-res music files downloaded from HDtracks. Add an optional BT-100 Bluetooth® dongle and stream music from any compatible smartphone or tablet.
