Having owned both Bluesound and Cambridge Audio streamers, I definitely prefer CA. They sound better, have more useful features, the app is better, they don’t die after 3 years as 2 of my Nodes did, and the updates are seamless, whereas I was afraid to update the Nodes because they would frequently be bricked for a while after doing so until Bluesound came out with the next update to release it.
Customer service with Bluesound was variable; occasionally responsive, sometimes frustratingly difficult to reach. As you can infer from my previous comments I needed them a lot. I can’t comment on CA customer service because I have never needed them
